We do most of our discussion and work on the Apache CloudStack mailing lists. Specifically, developer discussions happen on the cloudstack-dev mailing list. If you're looking for user support, the cloudstack-users list is the best place to go. (You may be tempted to send mails to both lists looking for help. Avoid that temptation. It's much better etiquette to direct emails to one list only, and to use the appropriate lists.) For guidelines on participating on the mailing list, see Mailing List Guidelines.
Please note that all of the lists are high-volume.
Before posing questions to the mailing lists ensure that you have looked through the archives. A very searchable archive of all the cloudstack mailing lists is available at markmail
Spread the word on how awesome CloudStack is. Below are the proposed open plans to gain visibility. By promoting CloudStack you can help to show the world that there is a "real", stable, user friendly, easy to use, feature-full production ready cloud platform.
We maintain several community IRC channels for real-time discussion and support, but please note that if it didn't happen on the mailing list, it didn't happen. Decisions are made on the mailing list (cloudstack-dev). But if you're looking for real-time answers to development or user questions, IRC is a great way to find help. All channels are on Freenode.
