How to allow only users with with certain email addresses to register?
 

Good Day Fellow VB's!
I am currently trying to set up a Bulletin Board for an INTRANET site at work. We're using it to allow employees to have a place to post new and terrific ideas to make this a better work place!

Question: How can I allow only users with our company name in their email address to register as users? (i.e. say our company name is SmithInc. and all our email addresses are in the form of [email protected]. We don't want anyone registering with [email protected] etc... only email addresses within our company). ;)
Thanks again,
