Ah, that fixed it
One last question: if I was going to link to a page of content in a side block, what would I link to? Just "?page=links"? That's what I do for my current non-vbulletin home page; it's got a similar content system. But with vB, if someone came to adv_index.php?referrerid=1, wouldn't going to ?page=links and taking off the ?referrerid=1 cause the referrer to not get the credit if they register later?
Or is that not how it works?
