Wordpress Mingle Mod

Simple mod to add Group discussion feature to Mingle. This would consist of adding a link: 'Start group discussion' which would open a new layer on the message page. This new layer will display a list of a user's 'friends' together with checkboxes to add their names (Mingle users) to the 'recipient' field of the message form. All the selected users would then receive the message and be able to respond to it.
