From now on, we are using Mantis to track bugs. It requires registration and is a little more involved than this board.
http://bugtracker.c-rpg.net/The idea is that this board is an issue board, where problems can be discussed and reported. The important thing is that bugs are fixed only from bug tracker, not based on threads on this board.
If you encounter something you think might be a bug but are not sure, make a thread here. Once you decide that the issue really is a bug that has not been reported yet, please add it to the tracker.
When adding bugs to the tracker, please fill in as much relevant information about the issue as you possibly can. Do not assume that some related thing "is known". On the other hand, do not add "personal" issues as bugs, place them in support project instead.
If you are unsure of whether something is a bug, post in this board first. Do not spam the bugtracker with invalid bug reports, they just slow handling of actual bugs.
