That's a bit tricky, since we do not require artists to include their real name when registering. But there are ways. Ifyou do a search on our memberlist
memberlist.php?mode=searchuser you can search their username or email address, if you know it. You can also search the gallery
http://www.asingularcreation.com/Gallery/search.php. If the artist you are searching for has uploaded images, it is possible you will find him/her that way.
I do want to add functionality for finding artists by name. Hopefully that can be something that we get done soon.
all the best,
Joe
