I'm a new member so I don't know if this was asked before.
In the forums there are links to relevant quiz categories. Do you think the same thing could be done in quizzyland, to publicise the forums for quiz, only users. There could be a link to Book Corner in the Literature category.

Those links used to be there, but were lost when we moved to the new Forums and/or Terry was rebuiding Quizzyland. I've put links up in Quizzyland as a temporary fix (they're at the top of a category page).
