Getting CodeIngoter to play nicely with facebook

[eluser]coldclimate[/eluser]
Phew - after 2 weeks of solid coding we've replatformed our facebook application from a big script to CI (we've used it on lots of other projects) and relaunched.

Along the way we've had to find lots of little hacks, odd code techniques etc to play nciely with FB (vars in URLs breaking things, using the FB library etc). I wondered if there was any interest frmo anybody here who's doing simalar things if I write up all the tweaks etc we've made to make it smoother for other to get started *it was a bit of a steep learning curve)?
