Ability to post or send Global Messages to the client portal rather than each client individually. I spoke to tech support and they advised to post the idea here. This would be useful for disaster recovery if user's are cut off from their email and we need to make periodic updates to all of them. Currently you would have to do each company individually.
Thanks for the feedback. I totally agree, having something like that would be great help for communicating key messages to your customers before they log incidents. This is a feature request we're currently tracking, and I've added a +1 against it.
As a workaround, you could go to Configure > Customer Portal > Default Settings, and set the Customer Portal Default to be Messages, and use Messages as your mechanism to broadcast system issues or maintenance.
