Is there any way, using JavaScript or similar, to create a sidebar element which displays, say, 4 random page titles from that wiki which are linked to their pages? The idea is to use it on an answers wiki where pages aren't regularly linked to each other and where the "read more" module at the bottom of the page would be counter-productive as it would show the answer to the question before the reader has to click the question. So, could anybody help with the creation of a module like this? It would be much appreciated and would really help with keeping people reading the wiki. Thanks!
