To simlify build notification configuration, one can define a notification scheme once in higher level configuration; reuse it to send emails in various descendent configurations, and want the email destination being dynamic based on current build. Currently QuickBuild supports two type of dynamic email destinations, one for "users who checked in since last build", and "users who checked in since last successful build". However in future versions, we will enhance QuickBuild to take other dynamic lists (such as module owner, etc. ), and also allow end user defines their own lists through variables.
