Awesome hack, it works perfectly in my forum. Thanks!

great Idea,, does it work in 3.6 ?
I'll give it a try :D

hi, will the referrer id be stored in a cookie as well? in case sign up is not completed

feedback: works perfectly in 3.6.4, the 2nd part of the template edit instructions don't match the instructions given here as the code block is changed for vb 3.6.4 but just look for </fieldset></if> and put your final </if> as instructed by the instructions there and it works well.

*Installed* Easy as pie.. Works great for me - vBulletin 3.6.5 Thanks a bunches! Always, Bree

This works well. Only problem is that the ref id is stored in cookie. If other people use the same computer and registers in your forum, they also wont see the referrer field in the regn form.

What this means is that same referrer id will be propagated to any new user that registers thru that computer.
