Some stuff I did:
- http://faux.uwcs.co.uk/dupscan2.html - a scan for duplicate releases by track times (FauxFaux/NotDuplicateReleases).
- http://faux.no-ip.biz/mbreports/ - some other reports, occasionally up.
- FauxFaux/LanguageSearches - links to all the language codes.
It's best to contact me on IRC, I should be online, leave me a PM if I'm not around. (irc://irc.freenode.net/FauxFaux)
I feel that any of my reports, especially mergeproblems2, could make an intersting collaboration, they'd need some work before hand, and possibly some proper hosting, though. :)
