If you're still not sure what to do on CPAN Day this year, you could help me with one of my trickle projects: help us get META.yml and META.json files added to CPAN distributions that currently have neither.

Send me an email and I'll assign you a distribution. I've ordered the list of distributions based on how far up the CPAN River they are. Fixing these distributions results in more accurate river data, and will also help various tools and services.
