So would we put up something as Origin name#carlsguide?
Also, someone on the official forum was upset because he downloaded someone else's sim from the Gallery, worked it over until it was something entirely new and then discovered when he uploaded it that it still had the first person's name on it as well as his own. Personally, I like this feature (although apparently there are ways around it). Anyway, it's something to be aware of -- if you want full credit, start from scratch.
I just used the hashtag carls guide and found 5 by Twinmum and 1 by saltpastillen. I think we have a new Swap Shop.
