Thanks, I actually hadn't seen that. What I had found seemed to be allowing me to "sell" weeks. I don't recall what for but it didn't look like anything I'd want to do.

Now the site you found seems straightforward although I have a comment from one of the mods suggesting I can post prompts now (as of 30 weeks) and that site doesn't accept any until 75 weeks. And does that mean after 75 weeks I can post prompts each week or is it just a one-time thing? I'm finding this very confusing.
