SIP, Portlets and Survey Results

Thanks to everyone for participating in the second Dev2Dev Survey. The results are in. Most of it was positive—thank you! Many of you love our articles and visit Dev2Dev frequently. Please, make even more use of your membership. Participate by leaving comments and questions in our blogs, articles and forums. We value your participation.

Two challenges that the survey raised are now squarely in our sights for this year: Dev2Dev Live! and the forums. Some of you have already provided great feedback about how the forums can be improved. Let me know what we can do on the Dev2Dev Live! side.

Regards,

Adding Handlers and Processing MustUnderstand Headers
