lol?
the challenges I like.
Clone challenge: who can create the best clone?
the, can you crack this? Challenge: post a link to software and see if a crack exists for it.
and the last one.

I got a chuckle from the can you crack this challenge.
@4 I could imagine the horors on the mods faces when they see they have to move 30 topics around, and everywhere is the phrase Moved heading level 3. Yes, if in deed the forum was littered with that message I would go nuts.

Raise the dead: see how many old topics you can revive and post replies to questions posed at least 10 years ago before you get caught out and banned.

@6 Jade and Dark have done the best with that one. Anyone remember the drinking game from Liam??
@7 how did I forget about that one? In order to get banned you would need to revive a shit tun of topics though. Which makes it a good challenge.

The post a reply in every topic room, but have every reply just be one letter, challenge.

Well we could have the longest email address in existance challenge.
My brother had the longest email address I know of.
He actually used it to till he got a job that was.
i'[email protected]
That was actually his entire email address.
The longest domain for an email address claimed that spammers wouldn't get it.
I went to it in the early net days in 1996 so who knows if it exists now.
www.abcdefghijklmnopqrstuvwxyz.com
Why you would want to use that domain worries me a big deal.
It doesn't exist anymore I just tried to search for it.
The free internet challenge.
Get the internet for free.
Sadly that actually happened in new zealand between the years of 2001 and 2005.
I4free zfree, and others tried to have a free net over dialup.
These were all supported by bigger companies.
It didn't work in the end because of server overloads, system errors, and loads of spam.
I4 free died and went bust, zfree became clearnet which got owned by vodafone.
There are actually probably a load of experiments that went on and off in the early net rizing days before ai in 1996-2001.
I was able to catch some of them.
An example of these was the would you put your entire contact details on a random mp3 site like mp3.com or something, install a program and have it play music at you and get you to rate it for no reason.
I did this, and after a month of emails, random popups and the like was told to rate songs which I had been doing then told to put in all my information and I would get a free cd of music.
I did, and I got a free random cd of mp3 junk.
Rumor was it was put out by some music company somewhere but the venture didn't last long.
I still have that cd.
There were services like xdrive and stuff.
Hmmm I guess there could be really stuff up your computer challenge, I think pg13 did this but get a vm, load windows, and load a load of viruses on it and addware, and screw it up so bad that well you get the idea.
They actually did this somewhere, look at pg13lp.com I think it still exists somewhere.

The code challenge, the challenge were each person makes up there own code, making it impossible to understand them.

The pointless argument challenge: Always disagree with the last post of a topic, no matter if a discussion would even make sense.

One word challenge: reply to topic with only one word, no matter how sofisticated the question was.

3 more challenges, 2 are exact opposites from each other.

Not today challenge: no one reply to any topics. It will be a sad empty day for the forum.

Celebrity challenge: Make every topic reach 100 posts.

Dispel Misspell challenge: type extremely fast and do not fix any spelling or grammar mistakes, kind of like what I do! They are too hard to fix, I'm too lazy

Okay, I don't endorse any of these obviously, but here are a few:

Talk like a pirate challenge: take a certain amount of time, and pepper your post with pirate-ish expressions during that time. For every post where you forget and fail to do this, you have to add a day to the challenge.

Live for the swarm! challenge: Create as many accounts as you can before getting caught and banned. They wouldn't have to say anything in the forums themselves, but they would have to introduce themselves and hopefully get unrestricted.

Loquacious challenge: Every post you make has to be five hundred words or more, and it has to make sense.

Nerdy and wordy: Every post must contain at least five words of four syllables or more, each, which are used appropriately. I'd have no trouble with this one. Heh.

Random Antagonist: Each day for a set time (seven days), pick a random user on the forum who is at least somewhat active, and disagree with everything they say. Don't attack them and don't insult them, just disagree with everything they say, no matter how logical it might be.

Poetic and strange: Everything you write must be either a limerick, or in iambic pentameter. Or, if that's too hard, make it free verse. An example below:

BK3 is one of the best games I've ever played. There are some weird balance issues and too many guns, and oh my god do I ever dislike stages 11 and 12, but it's really the only one of its kind.

Rendered in free verse:

Our great adventure
On the pinnacle, deftly balanced with
A wobble only when guns rattle too often
And on the eleventh and twelfth day
God damn it, Karla
Singular in its echelon

Or something like that, anyway. I promise you if someone tried this and did  a half-decent job, they would look really, really weird.
