There used to be a site called Mr Messy's that had some pics from movies and tv that I haven't seen anywhere else. Does anyone know if the owner may still be around? I'd like to know if any of those pics are still around. There's a Yahoo group which is pretty much defunct now

https://groups.yahoo.com/neo/groups/mrmessys/conversations/messages/32

I think you can safely call a group with no activity for fifteen years
defunct

Those of us who were into WAM online >10 years ago will have used the Yahoo Groups which were an excellent way of sharing content at the time, but then along came YouTube.
I don't remember the names of any of the groups but I used to go to my university or library, save the smaller clips onto a 3.5 floppy disc and take them home. Seems very archaic!
