Yeah, what has jwz ever done for open source? </heavyirony>. The solution to "this thing is broken" can't only be "fix it yourself".
That's what I use to get from Mozilla forums. Then I moved the company off of any Mozilla tools since we could get help on our issues. Been almost 10 years back, so not sure if it's still the case.
It isn't "you've already given me a bunch of your time, so now you owe me even more", either.
I think that's missing the point... you can either provide an easy way to report bugs (for instance email is the easiest) or you can say the project is no longer being maintained. The complaint is about projects that insist they are being maintained but have no way to report bugs. That seems like a concious choice on the maintainer's side, not just a lack of volunteers.
How's he going to volunteer to run the bug tracker when the project maintainers don't respond to email?
'cuase I gave up on a couple open source projects I started because bug tracking and feature request tracking was eating up a lot of time and taking away from coding (or even fixing bugs).
