I noticed a lot of externally hosted maps have broken links. I was thinking that since we have cleaned up the top maps section, why not set up some way to deal with these maps. For example, have something like a "Lost Maps" section or a way to tag maps that have broken links. And that way, if someone happens to have a copy of one of the said maps and can provide hosting, they could restore the link to that map.
I'm not sure how feasible this would be, but it is disappointing to find what looks like a great map - only to find that the download link is broken.
