MSN Activity API and www.worldsbestapp.com

I came across this contest, then a week later I found Robert Chartier's BareBones example, which has handlers for the common Channel events and a an OnLoad to let you know it loaded. Its a good way to start and see that "it works".

I've been working on an activity but it isn't ready to submit yet. I've got some performance issues because it is still very chatty and the game functions UI isn't done.

There is an FAQ, with some key links.

IE Leaky Patterns : http://msdn.microsoft.com/library/en-us/ietechcol/dnwebgen/ie_leak_patterns.asp?frame=true

I've got some cleanup code too write to fix the leaks and I would really like to be able to do some performace tests on the javascripts to see if there are bottlenecks.

If you have any links to helpful stuff about the API or about coding very complex things in javascript, please post them.
