I downloaded the map Dungeon 2 from the Temple of Elemental Evil section and started to work on it. Which was stupid of me. The map comes out to 78x63 if you don't alter the dimensions, and according to Avenger, BGII only supports up to 80x60, making the map unusuable unless you modify it. (of course, I learned this AFTER I put three or four hours into the map)
I would suggest that you just attach a note, either on the page that lists the map or in the .rar file itself, warning people that BGII will not run the map unless it's cropped to the appropriate size.
Also, a number of the links on the various area download pages are broken, leading to 404 errors. Just thought you might like to know.
