Hello, Thankyou for replying,

The vbulletin registration is cookie based, but my company already has a cookie based registration system, I'm going to be modifying the vbulletin one to use the one we currently have.

That is not my enquiry though.

What I would like to know is if anyone has written or posted a set of guidelines about writting modifications for vbulletin. I'm hoping for something like;

the easiest way to create mods without modifying to much exisitng code is.......

-or-

mods written this way will give the least problems when vbulletin is upgraded......

thats the sort of thing I'm looking for.

Cheers for any assistance.

Steve.
