welcome MaidenLady !
it all depends on what you like....cruise around the site a bit, check out the forums, join an RP, read a few submissions on the main page, post a few submissions, dont forget the mindless chatter too!...whatever your poison...we have a potion for you!
Also, try not to panic, when weird people come bearing gifts...flamethrowers, frozen trout, flying monkeys, and worst of all...stale donuts and lately, tacos.
If you have any specific questions/ideas/comments/suggestions/issues....fire away. All queries will be answered by your intrepid new friends!
I will take a wild guess and say...you are probably an RPer. Am I correct?
once again, welcome!
