We have just added a new field to the user profile: CPAN author ID. You can put your PAUSE author ID in this field. When someone views your profile, they will see it and it will be a link to the corresponding page on metacpan.

Do you like this? It can be removed if it is unpopular.

Update:

I have turned off users' ability to set this value themselves.
The field itself is still supported, and you can see it displayed on certain monks' homenodes.
If you would like to have your CPAN ID on your homenode, please just /msg gods with your request. Thanks!

Update 2:

As a convenience, I have added the CPAN IDs to user profiles based on the info provided in this CPAN api (about 30 monks) and in this MetaCPAN api (about 185 monks). Interestingly, there was almost no intersection between those two sets of data.
