Saving/renaming brushes in PS 7

Sorry about this. I did go to the memories and looked and did ask around with a few people, but I just can't seem to figure this out...

In one of the communities I'm in, a few months ago I found a post about saving brushes into sets and then renaming the set. So for example, if I downloaded a brush set that had username_brushname, I could change it to whatever I wanted it to show up as in my brush list (like I could name it Textures torn page username) or whatever.
Unforunately, I didn't save the entry and now I can't remember how to do that. I've found a few posts on saving sets, but when I re-open Photoshop it doesn't save it that way. The weird thing is that I didn't have to rename the file itself. I went back to where I have my saved brushes, and they have their original names, but in my brush list in PS, they have the name I gave them.

Any ideas?

Thanks for your help!
