First time on Dreamwidth

My my, I've grown so used to other sites that I'm not entirely certain how to get this one to do what I want! I suspect I can create different 'profiles' perhaps? and attempt to post as different ones of my characters, but I haven't the faintest on how to actually accomplish this! I suppose I'll need to start reading up on what to do, if I can figure out where to start...

Wish me luck!
