GlassFish core project (http://glassfish.java.net/) had the following feature:
When a new forum thread is created, an email with the content of the thread would be sent to the email@example.com alias. Developers would be able to see the forum question(s) and respond via email. The email response(s) would show up as respons on the forum thread also.
GlassFish Forum: http://www.java.net/forums/glassfish/glassfish?force=915
Email alias: firstname.lastname@example.org
Using the above feature, GlassFish team was able to provide great community support to the user base. After moving to Kenai, we do not have this feature and seeing many un-answered forum threads. We need this feature back.
