Hello ,

I saw on a lot of other boards a reference system . When you first register you are being asked a reference user. Can this be done here ? :)
It would also be nice to know how many users did a person bring on the forum .

Regards !

You could create a Custom Profile Field asking for a "reference member" and require it on registration.

Yes , I could but in my case I am interested only in the number of the people brought :)

It's not incredibly convenient, but you could then do a search of the Member list based on your custom profile field by searching for a username and you'll see a list of users who entered that name in their profile field.
