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 am avaliable approximately between 19:00-0:00 GMT -6 (Daylight Savings in Effect) And sometimes between 12:00-15:00 as well. Anyone avaliable during this time.
With GMT-4, I'm generally on somewhere around 7:10 PM or so to 1:30 AM GMT, plus a little after (likely), minus some in the middle (homework) on weekdays. Weekends are of little concern, I think (I'm on a lot then, as long as you are not at the other side of the planet from America's East Coast).
