I recently updated to 2.6 and was flooded with emails from people trying to register (so they could comment) asking why they were sent to a dashboard. Who on earth thought up this crazy idea! It is highly confusing to subscribers. It isn't immediately obvious what they are meant to do when they get to the dashboard. It merely gets in their way when they are trying to post a comment, Pleas remove this feature as soon as possible.
And one more thing. I get copies in my email with all comments that are posted apart from those I post myself. That means I have no record of my own comments and that is a nuisance if comments get deleted by accident.
