The Barracuda and Octopus original threads/projects were born in the Nginx group many months ago. In the meantime the Aegir community moved to http://community.aegirproject.org, and the BOA projects moved from GitHub to Drupal.org.
I believe it is a good idea to create a dedicated BOA group here, at our Drupal home, to not hijack discussions in the Nginx group and c.a.o community, but instead extend the Aegir eco-system with specialized space, where we can concentrate on BOA specific stuff, tips and tricks and general community support.
I hope that with your help this group will be a good place to meet other BOA users, discuss your ideas and problems, so there will be a better place to post discussions like this one: http://drupal.org/node/1186524, because issue queues are better for issues and features requests, while g.d.o is still better to join community and discuss BOA related topics with more freedom.
Welcome and enjoy!
