Your profile doesn't include your email address, so I'll have to do a bit more stuff to find out if I ever received your sign-up form.In answer to your question about how long it takes, if I'd received your sign-up form, I would have sent you an email saying that it takes as long as a month.
That's a rough estimate, though, because sometimes people indicate that they want only certain kinds of groups, and I won't start a group until I have at least four people for that certain kind of group. There are people who have signed up for a Hatrack nonfiction only group (for example) who have waited much more than a month.
I hope to be starting some new groups this week, though, so if I have received your sign-up form, Jenwithglasses, you are likely to be hearing from me this week.
Sorry that it takes so long sometimes.
