Just an idea,
   Would it be possible to add an affiliate section. This probably would look more like a regular webpage, but if forum users were looking for a specific product, if they were to access it through VinylForums's webpage, it would bring in a small amount of funds to help offset the cost.

For example, if I need a vector, I could go to this site and if I ordered it by using this link, VinylForum's would get a small amount.

It may not be much, but a lot of little amounts over time add up.

Just throwing the idea out there.
