Now that I am being paid to develop it, here are my initial thoughts on a Private Messenger package. Thoughts, ideas, contributions?
-Send a message or invite any online user from a textbox located at the top of every screen.
-User/Subsite Group selection widget.
-AJAX filter-as-you-type search
-Confirmation for sending to entire subsite group.
-Message textbox
-"User is now online" messages.
-Incoming messages field with history (dropdown window)
-Select user that was announced as online and send msg
-Users can block unwanted users or ignore all messages.
-"Block User" button
-"Unblock User" button
-"Ignore all messages"
-"Accept all messages" (except those from blocked users)
