Hopefully it's OK to put a feature request in - that's why I have marked this as a "non-support" topic...
I have a WP blog (2.6.2 currently) where I'd like to enforce a given email domain for new user registrations - i.e., as a poor man's membership blog. Members will be issued an address from a given domain, so when they register on the blog, they'll be automatically validated (provided there's no duplicate of course).
Blacklisting seems well integrated, but would it be (easily) possible to limit registration to one (or perhaps a selection from several) specific domains? Is there a hack to accomplish that?
Thanks in advance!
