I agree that the first email was rather vague. I wasn’t sure if I was going stay either, but I’m glad they cleared that up.
For alternatives, I suggest DA or Mediafire. DA can show promos but MF can host any file you want and hide stuff too so you can use it to share certain files with only certain people and not have to email everyone.
I wouldn’t recommend mediafire. More than once they wiped all of my files without ANY notification! That’s just unacceptable. I’m considering DA anyway. It’s never good to leave all your eggs in one basket. (Actually, you guys are free to post my freebies anywhere you want. I don’t mind.)
