Using Private Message Sys but how to show users in New Message 'To:' field ?

Hi,
Sorry if this is blatantly obvious but how do I make a userlist available from the New Message 'To:' field ?

Currently it is blank with no checking as a user types in a name, no search etc...

Surely this is a basic requirement ??

Otherwise there is only the ability to Create New Message from the profile of a user as the 'To:' field is pre-populated.

There is no sitewide autocomplete. You can quickly add a recipient from one of your connections if you have any connections and you've enabled that functionality in the plugin. Sitewide autocomplete is planned in a future release, but sitewide autocomplete isn't something 99.9% site massagers provide because it just becomes a vehicle for spam and causes unwanted communication and is almost always exclusively limited to your friends/contacts as CBs is out of the box.

Thank you
