Not sure if this will be any use or not, but you can hide messages on wiki pages using the code <!-- INSERT MESSAGE HERE -->. Thought it might be of use case you wanted to use it on the Clack page. I'd let you know how to set text to hide then appear when you clicked a link on page but having trouble getting that working myself at the mo, hehe - Lt. SalakTalk 17:40, 19 February 2008 (CST)
