I just got spammed with an email announcing a new web site with a searchable catalog of Microsoft Dynamics add-ons, complete with ratings and comments. 

Each Dynamics product has their own section. It's clearly work in progress, but after only been up a month, the site already has over 200 ISV’s showing their offerings!  I hope to see that this site will grow over time with tons of more add-ons for each of our Dynamics products. Visit http://www.microsoftdynamicsaddons.com and let me know what you think of it!

If I was an ISV I want to get my product listed here, so register yourself!
