Admin Registrations Only

What's the best way to allow users to only be set-up by the administrator - no self-registered users?

My organisation want to try out the Forum for Safety Related discussions. We don't want users to register with any name other than their network login name - we can't ensure that they'll all follow instructions to do this so we need a way for them to request, maybe via e-mail to have a Forum account set-up and then for an admin to set them up using their correct username and e-mail.

I can Suspend Registration which prevents users from self-registering, and I guess I'll need to change the code to display a "Request Registration" e-mail link instead of the "Sorry, new registrations are currently suspended..." message and finally amend the admin user registration page to send a registration confirmation e-mail, to prevent false registration requests.

Or is there an easier way I'm missing?

Thanks for this. I've looked in the Web Wiz Forum download  http://www.webwiz.net/web_wiz_forums/forum_download.as p?mode=asp but can't find a download link for the Windows Authentication Mod. I looked in the Mod Forum but wasn't sure what the "official" mod link was?

OK. I think I've found it and I've got a sneaky feeling it involves lots of changes to lots of files.

Is there any possibility you'll be adding Integrated Windows Authentication in a future release before I start modding your already excellent forum?

Now all I've got to do is convince our fairly starchy organisation that the benefits of a forum are tangible - a tough nut to crack indeed!
