That's a good one. But other than the list, I would think that communities like this one would be good places to float suggestions for new modules.

The traditional way to find an unmet need is to have a continually annoying problem yourself. I've trained myself, over the years, to go looking for solutions to such problems on the net, before attempting to write my own code. If I don't find a solution, then I generally try to adapt one that is more or less near to addressing my problem. If I can't find anything even close, then I sit down and have a good cry. But I also realize that there's an opportunity at hand to bring succor and enlightenment to a troubled world, and maybe get someone to help write my solution.

Usually by then the problem has gone away. But if it hasn't, then I try to fix it myself. That usually results in some Perl code. If that isn't too embarrassing to see the light of day, I sometimes publish it. (That is, of course, a link to my most successful Open Source project. Um, well, my only successful Open Source project. The point is still valid. Really. Trust me.)
