Where to report bugs
If you hit any bugs, want to suggest any features or simply want to ask any question please open an issue on the bugtracker of the relevant project at https://github.com/mana.
If you report a bug please make sure to give as much information as possible (such as used version, used operating system, ...)
Before we switched to github we used http://bugs.manasource.org/ for reporting. So if you want to look through old bugs or feature suggestions feel free to check there.
