Here is a guide to some player run shops. This is not exhaustive, this will surely not be up to date (shops tend to disappear as fast as they appear) and it will be down to the list of the shops I know or visit from time to time.
THOUGH, if you want a shop added, just e-mail me with a description, a contact icq or e-mail and the coordinates of your shop and I'll pay you a visit then post the article here.
