Do not go on teamtalk, I'm telling you... just don't. You will not like what you find.

Just like with everything else, your experience will depend on the people you choose to associate with. I avoid the public servers and most private ones like the plague, because most people seem to want to congregate in large groups and/or cause unnecessary drama. I run my own server, and it requires every user to have valid account credentials to connect. If you don't have valid info, you're simply not getting in. This helps to cut down on the nonsense and makes it very easy to remove users if they don't play nice.

I'm not sure how basic you want this info, but here's my best attempt to explain it. Users connect to a server to talk with others. You'll need the server address, port numbers, and account information if the server is configured to authenticate users. Think of each server as a conference building with multiple rooms. Everyone can be in one room or channel, or you can create multiple channels and provide places for multiple groups of people to do things. Everyone is on the same server, but you can have many individual chat sessions. Communication is restricted to the users in a specific channel.

I've only found a couple of downsides to the otherwise awesome system. The first is that information is not encrypted unless you pay $150 or something ridiculous for an encrypted version. The other is because of the nature of the system, you could connect and find no one else to talk to. People can come and go as they see fit. Oh, and the developer isn't that great from what I can tell. He hasn't done anything to improve the accessibility of the Mac version, and just seems resistant to feedback as a whole. Despite all this, I still really like the system. There are a lot of configuration features, and the audio quality is excellent! It's a shame someone else more willing to interact with folks isn't running the project. Finally, Team Talk is not technically just for blind people. Anyone can use it, and I don't understand why it's mainly blind people that do. Maybe it's because most people don't care about quality and features, the initial configuration confuses some, or the lack of encryption by default turns them off, or it's not widely known. I don't know. It's a shame, because it's such a cool system. My apps of choice these days for Internet communication are Team Talk and Zoom.

hi
isn't teamtalk open source?

As far as I can tell, the client is open source, but the server is not. This is a bit silly.

Teamtalk is like half opensource. You can't actually compile and use the source code unless you pay $1000 for the SDK. What is opensource is all the different clients, but they all use the SDK underneath.
As for servers, yeah I'd avoid public ones, unless you want to get involved in some toxic, non-family-friendly internet fun.

hey daganight, i have a private server.
if you want to go there, just say so.
all people on the server are my friends, and are trusted
no i amn't trying to addvertize the server
anyways, the choise is yours
thanks

Blind or not, doesn't matter. As long as you communicate with humans you're going to experience that.
to me, It's so ........ how we all think we are different than other humans but we're just the same.
Fill the dots with whatever you like.

agree with @5. i have a private server as well and i only invite people i think i can trust not to cause chaos. each person has their own user name and password and if they go too far, you're  gone. maybe a warning or 2 depending on the situation but i can't stand the baggage, lies or just plain nastiness that people try to bring on.
