(If you've already made the account) There's this guy called lacks that will help you if you're in need of help. There's those five tabs at the top, home, activity, submissions, forums, and chat. On home it shows popular stuff that's been happening, on activity it shows everything that's happened on the website, on submissions there's a bunch of games with pictures and keys (cont)
I'm not really sure about forums as I've never used them, and when you go to chat, you'll read the rules, and then type in /accept to join the chat. On the chat, there's four tabs that you'll see, the only one you'll really use is "off-topic" for just chatting about nothing. If you've already made the account I'll go on there and see you.
forums are where you go to get help, aside from chat which is the best place to get help.
there are a few options, theres one for asking coding help, one for glitch reports, one for fixes problems and one for sharing info on programs
