Let me start by saying that I really don't know what I'm doing.... 
I'm
the jack-of-all-trades for my nonprofit & am implementing MOSS
& WSS with the assistance of a consultant. I've had no training
& am trying to fumble along by going through some books.
That
said.... I read an article in an ASP.net book about how to allow
visitors to create new user accounts instead of manually creating them
all in the ASP web admin tool. I followed the steps in Visual Web
Developer Express & created a form called CreateAccount.aspx. When
I checked the form in my browser
(//localhost:1823/SPusermgmt/createaccount.aspx), I was able to create
a new account.
Then I went to ASP.net Configuration (from Visual
W.Dev) to see if the new account was there & it was
(//localhost:1781.....)
Now, I'm wondering how to "tie" that to
my extranet/SP site, so users can self-register. I also want to
pre-approve their account before they can access the site.
Any help is appreciated. Please remember I'm a total beginner. (And I apologize in advance, but I have cross-posted this because I have a feeling I'll need this explained to me in several different ways!!!)
