We have just deployed a new dashboard home page is now live with what we hope is a clearer explanation of how to use 33mail along with some css3 rounded corner goodness (note that Internet Explorer users will be stuck with square corners until Microsoft gets its act together).
We hope to deploy further widgets to the dashboard page in future to give at a glance useful information such as bandwidth usage and most used aliases. Any feedback on the new layout, good or bad would be much appreciated.
