One of my bugs (98053 freesweep forwarded normal help) is tagged help. It is half fixed with a work-around, upstream did not seem interested in fixing it, but said they would have a look. This was a few months ago. I tagged the bug help, to encourage people looking for bugs to help with to help by providing me with a patch to fix the bug I could send upstream.
Was I right to tag it with help? I am not sure. More details at http://bugs.debian.org/98053 -- The enemy's gate is down http://people.debian.org/~edward/
