I downloaded a huge set of 1000+ brushes, but when i opened gimp, they were not in the brushes menu!. I put them in the right folder (C:\Program Files\GIMP-2!.0\share\gimp\2!.0\brushes), and they all are !.gbr!.
Here is the link to the brush set:

First of all, thanks for the brushes!.
Second, you need to make sure they are out of the zipped folder!.
Where I would put mine, is in the documents and settings folder!.
C:\Documents and Settings\YOUR USERNAME HERE\!.gimp-2!.0\brushes
And just copy and paste them in the right folder!.!.!.
I have 2!.4 myself!.Www@QuestionHome@Com
