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.
If you took a look at the tech support and SQSA threads, you would see that Showdown was recently DDOS'd (again), but Zarel is working hard on getting it back up and running. He's not magical, though, so give him some time. :]
