Our mailing list is hosted on SourceForge. You can use it to ask questions to the Micro-Manager developers and other users, and provide comments and suggestions. We also use the mailing list to announce new releases. The list has a volume of about 150 mails per month. The archives of the list might already contain the answer to your question.
Support is also available from the company Mission Bay Software. Services provided include subscription-based configuration support as well as custom software development.
