Not I, though I do have '92 model PRS CE24.
Is anyone here a member of prsregistry.com? I have a question about membership. Feel free to PM me.
I wouldn't do it.
Guys at Birds and Moons said there were some shady things about the people involved with that site and the way that they keep/present the serial numbers of different guitars and their owners.
I'd have to dig up the original thread, but I think it mostly had to do with someone digging up photos and names, and putting them in the registry without the guitar owner's permission.
It would be like me posting a few pics of my PRS here and then finding them listed under "A.W. Baimun - Indiana" on their site without my knowledge.
I think you get a free membership when you pass the bar exam.
