tkchat id for [Richard Suchenwirth] (aka [RS] here on the [wiki] pages. I make it a habit to sign longer articles with my full name, so I can get a list of them by clicking on that page's title; while [RS]  stands for shorter discussion notes. 

Oh, and one thing: if you read one of my (or other) pages and have comments, questions etc., don't hesitate to edit them in - best at the end, that's where I look first when a page changed.
