Since Maia is open source, the most valuable support venue is to participate in our Mailing Lists. Before posting to the lists, you should first check the FAQ to see if your question has been asked several times.
Changes to the codebase are tracked by this web application; if you found a bug, then you can submit a new ticket. Check existing tickets via the "View Tickets" link above, and you have a new bug, email the lists above and we will hone it down and make a ticket.
Commercial support such as installation, maintenance and consulting is available by contacting Robert LeBlanc and/or David Morton.
