Do these mods or HOW TOs exist?

[Marco van Herwaarden]

1) If you mean that they should be using a real name as member name (or een in a real name field), then my question to you would be: How to recognize a real name?
If you want them to use real email address, switch on email verification in vBulletin Options. They will need to click on a link mailed to them to finish the registration process, so you will know the mail is valid.

3. Are you sure you want this? How many post and member do you expect?
