It would be really nice to be able to notify all system users with a notice upon logging into Marketo - such as system maintenance, or template upgrades which could impact the ability of marketing users working in the system. In the Admin panel if one could program a notice into the 'What's New' section of the My Marketo tab or a jump page such as what appears in Salesforce.com when system maintenance is planned it would help Marketo Admins communicate information without having to send an email to all users. 🙂
