I had always hoped that people would eventually file Lix bugs on github. Few people do that (geoo and Dullstar) and instead we discuss most bugs in the forums here.
A forum isn't ideal as a bugtracker. Closing bugs and locking topics should be different, e.g., people should be able to complain that a closed bug isn't fixed after all. It's more sensible to write "Solved:" in front of the topic. Or you end up making several boards for open bugs, for closed bugs, ... which isn't bad, but produces a long board list if it becomes the standard for most projects.
There's also no fine line between discussions and bug reports. Some things are clearly open discussion, some things are clearly bug reports with steps to reproduce etc., but many things are in a continuum. That's limiting even on Github.
I'm not even sure if it was good to split Lix Levels and Lix Main. Reason: We discuss bugs on Lix Main, and Proxima posted tilesets (that I haven't merged for 1.5 years, what am I doing with my life) on Lix Main; only levels somehow go in the separate forum. And for me, many level threads are really bug threads: People want a backroute fixed in a pack that I ship.
On the other hand, I'm not so sure if namida's closing of the NL bug board was ideal (despite the planned end of maintenance); as a result, I post the rants we file the bugs on the main board now.
Hard to say what's best. I think WillLem should get the boards for open bugs and for closed bugs if you really want them. But really, sleep over it. One alternative: File and track your bugs in a real bugtracker, accept that few people will read that, and treat the forum more loosely.
