Chris Redmond
Chris Redmond retired in early 2012 after almost 39 years working in internal communications at the University of Waterloo. He was responsible for the Gazette newspaper from 1973 to 2004, and edited the online Daily Bulletin from its founding in 1993 until November 2011. He also, apparently, talks to trolls.
Simon the Troll
Simon has lived beside Laurel Creek, on what is now the main campus of the University of Waterloo, for some hundreds of years, if everything he says is to be believed. He has seen what there is to see, and told a good deal of it in Water Under the Bridge, a series first published in the university's Gazette during the 40th anniversary in 1997.
