sort by subject in privatemsg Is there any possibility to sort all the messages by subjects? For example, there is a button on the main page "send a message to author". Subject from the sender is defined as "main page". If several users send message with this subject, can i see in my mailbox one subject "main page" and then see the list, who wrote it?
Messages in the inbox can be filtered by subject.  To do so, if you are on the default path (messages), just click the blue link for "Subject" at the top of the table.

Alternately, if you want to always filter by subject, you can change the messages link to this:
messages?sort=asc&amp;order=Subject.
