Thanks, all, for the encouraging words! It's great to know we've got some fans.
Regarding Episode 5: Recording is done, hopefully it will be out by February. School is the worst thing in the world.
@MsLinn: I use Adobe Flash CS5 now to animate it. It's a great program, and I would recommend getting it, but it's kind of ridiculously expensive. (Fortunately, we were able to get a discount on it) If you've ever gotten an Adobe Creative Suite package, though, Flash is always included!
