How to mark posts and private messages as unread?

[anitya]

Not sure it is even possible to do that at Proboards but it will be a nice feature to know and have.  I like when I can mark my Gmail and outlook messages as unread so I can revisit them / reply later.   May be yogibearbull can answer this upon his next visit.

Threads and Message-chains can be marked Unread from Action just below the Menu bar (near the Search window). This is not possible for individual posts or messages.
