WordPress MU

I just installed WPMU a few days ago at http://blognola.org and I'm having problems that I can't track down. WHen I create a blog at the Site Admin>Blogs page I get an e-mail letting me know it's been created, so I know wordpress is able to send stuff out. When a potential user uses the wp-sign-up.php form, no email confirmation is sent. In fact, I see no indication anywhere in Wordpress itself that they attempted to sign up. Is there a place where pending users can be approved? I see entries for them in the wp_signups table - but is there anywhere else they should be to trigger this e-mail? Can they have the email re-sent. If I delete them from this table, can they try again? Is this information anywhere else in the database?

Sorry for all the questions. heh

I'm running:
WPMU 1.1.1
PHP 4.4.6
Apache 1.3.37

When you looked at your email server's error logs, what did you see?

I don't see any errors in the the cpanel error logs, no. There's no e-mail specific error log that I am aware of.

The CPanel error logs are for web traffic. Ask your host.
