So lately, I've been trying to help the perl community by fixing modules that have had their RT queue neglected because the author has gone MIA. This requires I take over the module to fix what needs fixing. In order to take over a module, you need to do the following:
1. Open RT tickets about the issues you are having in the appropriate queue.
2. Email the author(s) with as many email addresses as you can determine, cc'ing firstname.lastname@example.org
3. Publicly post that you're looking for the author in a frequented blog source
4. It doesn't hurt to post to perl monks either.
If all of this fails and multiple weeks go by, email@example.com will hook you up.
This is summarized from The PAUSE FAQ
I'll be doing this for a few modules over the next few months that have been bothering me because they have one thing or the other out of date. I've also been writing a dependency tracker for my own purposes, using the META.yml files that come with modules. A surprising amount of modules do not have a proper META.yml file.
I've already started this process on a few modules. Where I could contact the authors, I've found them to be helpful in most cases. In some cases, they fix what I had an issue with. In other cases, they just pass the PAUSE baton on to me and I can fix it myself.
