Bit of shame really that JOSM has a seperate subversion, bug tracker and wiki. Obviously it’s a logical separation, but these community driven bits n bobs get more active when they’re lumped in to form a larger community don’t they? Actually I seem to remember a (very old) mailing list post where the original JOSM author was saying he would have liked to put it in the central repo, but there were some administration permissions issue.
Also… what’s the point in having the jar files checked into OSM’s subversion. Just creates confusion no? Maybe a little readme.txt file there would help.
