FogBugz should include a rudimentary URL-shortening service to use for permalinks and deep-linking to any other particular page.
At the simplest, it could create links like:
http://fogbugz.mysite.com/x834j
or even http://fogbugz.mysite.com/?link=12345
This would be way nicer for pasting in emails than nastiness like particular wiki changes:
http://fogbugz.mysite.com/default.asp?pg=pgWikiDiff&ixWikiPage=2317&nRevision1=28&nRevision2=31
and search/filter permalinks: http://fogbugz.mysite.com/default.asp?pre=preSaveFilter&fOpenBugs=ON&ixProject=68&ixPersonAssignedTo=46&sort1=8&sort2=4&sort3=6&fGridView=1&sView=grid%2Doutline&iTypeOrder=1,29,2,3,7,5,9,54,4,26,6,16&gridPlugin_7=12&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&
Even cooler would be some basic click-tracking for those shortened URLs.
