The Product Developers email list, which was started in early 2007 as an outgrowth of Martin Aspeli's session at Plone Conference 2006, has really blossomed into a vibrant, active community of folks working collaboratively on add-on products for Plone.

It's a tremendous resource if you're developing an add-on product, looking for advice about an existing add-on product, or looking to make suggestions for how you'd like to see an add-on product evolve.   I plan to follow this list a LOT more closely from here on out, and I encourage you to as well.

You can subscribe via email or read it on the web via Nabble.
