How would I go about doing this?
 

Basically I want to make a hack for vB, that goes through the userlist and looks for users with 20+ posts; and compares their post count and referral count to modulus, while increasing a value.

Eventually it will be used for a raffle - for every 20 posts you have, you get entered one time.

I know my way around PHP, so that part is no problem - its just my first time working with vB, so not only do I not know the layout - but I don't know how to make hacks in general, how to add values to user accounts, and I also don't know how to access information from vB, such as post counts, usernames, etc.


I couldn't find any reference to... Anything regarding hacks in the manual, so can anyone here help me out?

Thanks

I'd just like to note, that in case you missed the purpose of this post - I DO know PHP, and I do not need help with that part.

I simply need help writing the vBulletin parts (Mainly how to access vB information without writing a separate MySQL class)
