Shannara:
Yes, there is a reason for the limit -- one of them is so that people who are denied adult access have less reason to go open up a new account in an attempt to get around it.
Another reason is that two weeks to get to know the site and the adult rules helps to avoid problems.
Alrighty, that makes sense. Thanks!

Perhaps the people could create accounts ahead of needing them. Gives them time to get acquainted with the format and rules of the site
I considered this, but I'm inviting people from a FB group, and I don't know which of those who are going to respond I'll ultimately accept so it won't work in this case. I think Shannara's suggestion - non-adult to adult after a few weeks - will work better. Thanks, though.
(That said, you're right - I wish I could get them acquainted with rules and formatting ahead of time.
C'est la vie.)
