I'm trying to understand the association between BGG user and game designer/game artist.
(1) Is it correct that the link between a game design and a BGG user has to be done by an Admin?
So if there is a user "John Smith" and a game designer "John Smith" who has been entered into the system as a person, the two are not linked just because the names happen to be the same.
Yes, of course they are not linked just because the names happen to be the same. Otherwise I could change my user name from Russ Williams to Reiner Knizia and magically become a prolific successful game designer.
