Hmm, i think thats a good idea
I agree with Kevin that it may be quite hard to explain maths and science equations etc but we could maybe give it a go. Anthony was helping Heather in her diary with a science equation and although it isnt as complicated as some, i think he explained it really well.
Theres absolutely no harm in trying it and if it doesnt seem to work then it can easily be removed or 'unstickied', right?
Anyway thats just my opinion
