Message can't be delete in 2.0 beta

Hi, I want to delete some message. But it's impossible in 2.0 beta. Hope this feature can be add in future. Thanks.

There is also a private message function, which requires a monitoring function.

Right now it's done on purpose. It should be well thought out before a decision to add this is made.

It is recommended to do this: add an option in the admin panel to automatically delete private messages for more than x days.
