Finally getting my head around this!
WEEELCOME! TO THE WORLD OF TOMORROW!
Erm - something like that. But, indeed welcome to RPOL. Great community. Lots of active games. More dice rollers than at which you can shake a stick. And more humor than at which you can safely laugh.
First suggestion: enjoy the boring read and read through the Help and FAQ: this site is so different than other sites that try to perform these same goals, and it does it so much simpler; that it can be quite daunting at first.
Ask, ask, ask. If you're confused about something - ask away. Either here in this very post/thread - or in the community area and so forth.
And, of course - have fun!
