We have Q&A on StackOverflow, support via cloudbees.zendesk.com, IRC - and now a google group.
Why another thing? well some people wanted a place to chat about things - specifically the technical direction of CloudBees, new features, developing clickstarts or clickstacks. StackOverflow is not the place for discussions (chit chat is discouraged).
So please feel free to join the conversation - if you are building ClickStacks, or ClickStarts, or have feature ideas - feel free to join .
