CLICK ALL THE THINGS! (pardon me, I'm sleep deprived at the moment and we DID have a full moon... *strokes invisible beard*)
I would suggest clicking on any little helpful hint looking things near the top of sections... and uh... things are kinda sorted by order of whether you're looking for help/community things, group, 1x1, or something very genre specific. there's chat's too, but I haven't seen people use those very much... OH and make sure you go into your preferences thingy and fill out your about you/résumé thing ^^ it's uber awesome and lets people see what you like to do (or NOT do!). some people are very into pm rp, too. there's a little of everything, so poke people, start threads, and get messy (well, maybe?)!!!
welcome ^^
(ps there's a special area for SEARCHING for partners... I would click on those or hit the search thing at the top of the home page to find available people, or start your own search for buddies)
