JEMHC is hosted by the Plugin People on Amazon Web Services. Questions relating to support and availability of JEMHC addon should be directed to support@thepluginpeople.com or the JEMHC issue tracker in the first instance. Direct telephone support and/or conferencing are secondary methods that will be used where JIRA cannot help.
Of course, we want JEMHC to work for you and will try to answer all your questions, but may well refer to Atlassian Support when areas of responsibility are crossed, e.g. JIRA usage.
