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.
Just to make sure we are on the same page, when using a 24 hour clock, 2200 is 10 pm. Basically you add twelve to whatever the 12 hour clock's pm it is. However 10 pm your time does work as well, so I'll see you there!
