"A "wiki" which is basically an editable website that allows people to easily collaborate. You can use a wiki from anything to organizing a camping trip to replacing your water cooler discussions at work. See some more uses of a wiki here."

If they don't know what a wiki is, they probably don't want to create one. Secondly, if you must keep it, make the font bigger and easier to read. I had to zoom in it just to make it legible.
