In particular, I am asking about how much time do you have to wait until you get accepted to join the challenge. If s/he has to approve each mail address, this will take a lot of time.

Again, it varies. Challenge joins shouldn't take too long, as I imagine that processing those emails was one of the first jobs that got automated. If I remember correctly, my registration had a response time on the order of a couple of hours. Side note: don't top-post. It's very frowned upon in most mailing lists.
