Howdy!
yu fell into the right site. The best site out there.
all the information you need is on the main menu.. search for games in 'wanted players"... or the 'browse and search bar ,where you can customize your search
'in game' menu is great, dice rollers, PMs everything handy, and in one place.
don't be afraid to ask questions in the forums , there are always Players who will have an answer.
