And as I said earlier in this post...
The thread "Favorite Member Sites" in
Ask a Question forum
The little star feature saves it to your profile for your future reference.
edit...Ok in re-reading this...Your wanting to "favorite" a member?
I'm not sure I get that.
The star feature allows you to "favorite" a post...Maybe made by a said member?
And then you can go to your profile, and make your own comments as to why you "favored" it.
