Interested in buying and would like to know....
 

I was at a site yesterday who uses vbulletin and they had a service where you can sponsor a particular forum for whatever price you want. I would like to do this in my forum. How do I go about doing so? The site I was at is www.RapMusic.com. Thanks.

You can download the hack that allows you to add sponsors once you buy vBulletin. :)

Oh, so once I buy there is something that will allow me to do this? Will someone have to install that part? What is a hack anyways? Thanks. Oh and is there a paticular version of vbulletin I must buy?

There is always one version of vBulletin available to download, so don't worry about that. At the moment this version is 2.2.5, but 2.2.6 is due to be released next week.

When someone changes the original code of vBulletin, it's a hack. Hackers release these changes, with full instructions on how to install. Currently there are 903 hacks released on this site -- lots to choose from. :)

and there are also some Hacks in the request-forums, which you can implement, so a board can be as unique as you want :)

Thanks so much for taking the time to help. I am very interested and will be purchasing in the upcoming week. This is the best I've ever seen and can't wait to get started. Thanks again.
