Well.. I don't know what happened this week, but I had a number of new people ask to get into the Beta. I have only 100 spots to be able to provide beta code, and I have 75 people in now. If you know anyone that wants in, you should let them know soon. As I've said a dozen times now I'm going to work on getting it released to iTunes so I won't have this problem anymore.
I'm on vacation this week from work, but still trying to cover beta requests as I can. Sorry if it took a few days to get you a build.
