Insane idea!

hehe, i know this system and thought about using it too, but i cam to the conclusion that bugzilla is completly overpowered for us.

Yes, I agree. But such systems have many options in customization and they(it) could be brought into a state of very simple and useful for you application. Actually I didn't dug it at all and I cannot tell in sure.

and i think if there is one topic for every bug only rly stupid ppl will create a second with the same bug... xD

That is the problem. When you see(when I see) a list of topics which contain one bug per topic I have two choices to identify a bug: first is to read only topic names(which in most cases are non informative because of low users' CA qualification;-)) and the second is to open each topic and read about it. The second is boring but it's the only right choice using forum. Of course, YOU can maintain it by correcting topic names to make them look like a bug-tracking system:).

As for stupid I could add here also lazy. The human laziness today usually compensates with automation provided by computers and machines in general. And in this case needed automation could be provided by bug-tracking system:)
