Re: Moderating User Registrations?
Yes, of course.
Check options at "Admin > Login>.
You can read the manual:
http://doc.tikiwiki.org/tiki-index.php?page=Login+Config,. even if it reports only features for 1.8.x, not 1.9.0 (tehre are some more options in 1.9.0, which include "admin validation")
Hope this helps.
