I just went through and updated all of my uploads with (I hope) the appropriate prefixes. Nifty tool.
A note to all of you map authors:
If you have a map floating out there in the deepest, darkest recesses of the forums and would like to eventually see a section for it added to the map list, then please add the "Map" prefix to it. I intend to give the list a major update in the near future and it would make life much easier if this great tool were utilized. Of course with the ability to search by prefix the map lists usefulness will be diminished considerably, but it will still show preview images where available and give another avenue for new users to locate some of the great maps available.
