Re: Questions about vbgallery
1. "vBadvanced" is the name of all of the products here so the Gallery's full name is actually vBadvanced Gallery. Of the three current products, vBadvanced Gallery, vBadvanced Links, and vBadvanced CMPS, all of them are stand-alone unique products that do no require any other software other than vBulletin of course. So, yes, you can use vBadvanced Gallery without vBadvanced CMPS.
2. I believe Brian has one but he'll have to confirm.
3. Yes, it should be OK.
