Good morning! (Er, when you see this it'll probably be afternoon.)
Welcome to RPG! I'm Disc, as you can tell, and it's great to have you!
Erm, lemme throw a couple links your way, just to be safe:
The Hitchhiker's Guide to RPG Chat! This covers all you need to know about RPG's (in)famous(?) chat, in case you ever want to venture in.
Myrin's Guide to RPG! This covers all aspect of the forums. It's very simple, and will help you out a LOT if you have any trouble navigating.
How-To Guide: BBCode / Forum Code. That's just a general primer on how to code your posts and make them pretty freaking... well, pretty.
Once you're done reading those, I suggest you hop in and check out either our RP Tab to see what suits your fancy, or check out the RPG Chat! Either way has lots of vibrant roleplay, and I bet you'll have a great time here.
If you need anything, look out for people with green, blue, or red names - those are moderators, mentors, and admins, respectively. They're all staff, and will be kind enough to help you out, or at least point you in the right direction. :)
See you around some time!
