Hi, welcome to the boards.
So, basically, there are a few things I tell newbies.
1) Try your hardest to use proper grammar, chat speak bothers a lot of us on here.
2) When you post about something, it's better to KNOW what you're talking about. Especially on religious or political threads. If you don't actually know or believe what you say, you'll get jumped on pretty quickly.
3) A lot of people here have been regulars for a while, so of course there's friendship bonds. If you stay here for a while, trust me, you'll make some wonderful friends.
4) Long term threads (Rack up your posts, Twilight thread, Harry Potter, etc) have some really great people in them. Don't be intimidated by all the posts, don't be afraid to join in with the discussion!
5) We don't talk about just Disney here, obviously. We discuss our problems, current events, politics, religion, movies, excitments, etc!
6) I'm glad to have you! We love new people and I can't wait to see how you contribute to these forums.
