You can look at it as kind of play-by-email, where a web-interface is used to make the board look prettier. To start playing you should first get yourself an account, if you haven't got one already. Thereafter you could edit your profile and enter some biographical info, especially the fields 'Open for matches?', 'Rating' and 'Rank info' are useful for finding opponents. Next you can study the user list and use the forums to find suitable opponents to invite for a game.

More information can be found in the FAQ forum where you are also encouraged to submit your own questions.

Once again welcome, and enjoy your visit here!
