I would definitely prefer the weekend since I'm not prepared at the moment and due to schoolwork I feel weekends would be the most convenient. Friday would probably be the earliest I'm available. Friday(after class)/Saturday/Sunday I should be available for most of the day(3pm-11pm GMT-5, preferably not during dinner if possible). Let me know if you can battle during any of those timeframes.
I have to get my training regimen into gear over the next few days, is there an IRC channel or server you're usually on so we can just meet up there? If not I'm very flexible in the latter part of the week.
