There is no difference in the installer for Xeams Community and Enterprise Edition. It will run as if you have purchased the Enterprise Edition for the first 30 days. It will then get converted to Community Edition unless a license is purchased.
Henrik,
Create a user representing this group. For example, assume you have a distribution list on Exchange called sales@xyz.com , create a user representing this email in Xeams. Then, reports will be sent to everyone on this list.
