Sundays seem to be my most available day, though january is going to be a busy, busy month for me. I deliver pizzas, so more than likely if I'm free, it'll be morning/afternoon, and not dinner/evening. Midweek, I'm more often working during the day and free-er in the evenings. Otherwise, I'm down.
If I had a house, I'd say we should do a board-games/potluck thing, but alas, we're currently in a fairly small apartment.
