Can anyone help me understand what the word 'Liaison' means in this context? I found it in a contemporary American novel. The author is describing the youth baseball league in her neighbourhood. After describing the various roles parents play as volunteers, she adds this:
In addition, there were agents and board members who organized and administrated the league throughout the year, and a Liaison whose affiliates assisted with league operations and fundraising. Along the way, someone had the brilliant idea to make this discretionary servitude an honor by requiring that new recruits to the Liaison be nominated, thus elevating the countless hours of free labor to a form of exclusivity.
What exactly is a 'Liaison'? The dictionary doesn't help me...
