Hmmm, thanks again for the help so far... but my knowledge of JS is literally zero...

I've downloaded these files:

jquery.easing.1.3.js
jquery.easing.compatibility.js


.........and uploaded them to my /includes/templates/CUSTOM/jscript folder.

Now, where would I go from here? I mean, how would I attach the behaviour to the messageStack div?? Remember I have zero JS knowledge
