I was given a really good tip by a former trainer today as I struggled to get rid of permanent marker pen writing on a white board. If you write over the permanent marker with the correct type of pen (i.e whiteboard non permanent marker), and then wipe it off as normal, it will miraculously disappear.

A tiny but perfectly formed example of knowledge in the right format, at the right time to be useful – made my day!
