it would be great if there would be any kind of developer edition, I like your product but it is not customizeable enough to buy the Enterprise edition.
Especialy the notification rules should be totaly customizeable, for example that you can choose yourself which persons geht which email on customized events, this way most other help desks have a much better notification system.
With a developer edition it would be much easier for companies to fullfill their requests on the helpdesk.
