Simple question (refferal)
 

Hello,

I would like to learn if I can add a reffering person box during registration (to track who reffered subscribers)

that's a standard feature but disabled by default .... look here

thank you. this feature is great, however Id like to know if there is a way to add a box that will enable the person (in the process of registration) to write a name of a reffer that isnt already subscribed

There's a box there by default....Didn't you notice it when you registered here?

Im sorry I dont see it here

vB.org has probably disabled the referral function. Anyway, yes, there will be a box to type in a user's username.
