Hiiiiii
Welcome all of you! This site is fantastic. Not just easy to use but full of knowledgeable people who love helping new folks.
If you've already checked out the FAQ section in the upper right corner of the screen, you can check out the Wanted Players section to look for games that are "hiring" or post something in Wanted GMs if you have a specific game you want.
There are also plenty of threads available to ask for specific gaming help, too.
Make yourselves at home. :)
