Those parts of the site sadly don't operate at the moment, they haven't for some time as I recall.
Just to warn you I'll help if I can, but I'm not responsible for anything on this site I'm just a recently made moderator. If you need to talk about anything major regarding the site you'll be wanting Richard or Senderman, you can send them a message through the forum by using the "send mail" link near one of their posts. It will bring up a page with a form where you can enter a message that will be emailed to them without the forum disclosing their email address, though it will disclose yours to them so they can reply if they wish. Senderman is the one you want with any technical matters, but they're both really good guys and so long as you're not planning on pestering them about stuff unrelated to ag.net or that could be more easily discussed on the board they'll probably be more than happy to help you out. They might not reply right away since they have lots of stuff to do in their lives, but you'll get a reply.
Hope this helps some.
