The xOperator Project is moved to Google Code which is much faster (the tracker, not the subversion repository) and has some nice features (e.g. the customizable grid view).
Traditionally we use SourceForge.net for our open source project management. SF is a great side and I’m member of 9 projects there but it was time to move. Basically its a matter of speed. I work every day on tracker items like bug reports, feature requests and tasks for one of our projects and the sf-page is very slow in comparison to google code and also in comparison to our tracker for commercial projects (we use mantis for that).
Project resources of xOperator are now Issue Tracker, Downloads and Mailinglist (moved to google groups). Our homepage @ aksw.org does not move.
