Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I found multi to be fun, but I'll admit it took a while to hit it's stride. However once you get to stuff like Stokes/Green, Div Thm, etc it gets REALLY interesting.
hey! If you have IRC, you can find me pretty frequently on the #littlecup channel. If you don't have IRC I recommend getting it (actually though, you can use the link in the Smogon Metagame's description for an in-browser client where you don't have to download anything: ).
