I think there should be a section with a list of sponsors. I saw an add for a product I wanted, and now it is nowhere to be found. I do not know the name of it. Only the effect.

I think a list of sponsors would be a helpful resource. THanks!

If you know the effect but not the name, I'm not sure a list of sponsors would help you. If you know who was advertising the item, then you could go to their website.

You might want to make a post in the appropriate forum describing the effect, asking for it's name.
