Public User Groups - Mild Modification, please help.

[MikeWarner]

My site is for a car club based in the UK. The club is splitt into 13 regions - each region has a co-ordinator. I would like to set up a public group for each region with the co-ordinator as the group manager. Now this isn't a problem.

The problem I have is that the use of the groups is very limited. I would really like my group managers to be able to "PM selected user(s)" from thier group's member list. This would be a great feature. At the moment, you can only PM them one at a time.

If someone could help me with a hack to enable me to do this, please do let me know - I assume only template mods would be required. All I need is a button to "PM selected user(s)" next to the "Remove seleted user(S)" button on the attached image. Also an option to email them would be good. Maybe replacing the existing button with a drop down list would be better?

Any help would be greatly appreciated.

Many thanks.
