Hi, Don't know if you heard about Trac (http://trac.edgewall.com/trac) but it's IMHO the best tool for bug tracking/project management. Specially if you use subversion repositories.
Trac is a mix of a Wiki + WebSVN + Bugzilla. It's written in python. It's bright and lightweight: - entirely based on wiki syntax (useable in pages, bugs, commit messages, ...), - possibility to reference bugs, pages, sites, changesets (revisions) inside pages, bugs, commit messages, - possibility to close/change bugs directly with commit messages like " Changed blah and foo to do this or that. Fixes #10 and #12, and refs #12" - clear reports, an layout (CSS), - wiki plugins to generate toc, menu, footnotes, to tag pages, ... And afterall a painless migration from bugzilla, and an easy installation. Perhaps one day a plugable wiki module in cocoon ? Regards.
