I've got two "face" characters in my party with Diplomacy modifiers around +20, and those modifiers will continue to grow.  The aid another mechanic doesn't really seem to give them full credit for resources they've put into these skills.  Is there a mechanic out there, perhaps a skill trick or teamwork feat that might give the pair a little more benefit from working together?
