For my april fool, I decided to go with the plan of simultaneously annoying people and giving them something they wanted.
On
the website, I created an intercept script for all the webpages, so that you have to click twice to get to any page.
I'm more pleased with what I did to the
forums, though. If every post has a random avatar that changes every time you load the topic, you can't recognise the poster from the avatar, which is what most people do. Equally, if you add an extra line at the end of every post, it takes a while before your brain stops processing it as part of the message.
