Combining Codeigniter and CMS made simple (CMSMS)

[eluser]boony[/eluser]
Hi Folks,

I've got a client who needs a website redesign. The current site is pretty static but uses CMS Made Simple (CMSMS) to manage the content. They now want to add some dynamic functionality but want to keep CMSMS as they like it and are used to it.

My question is has anyone done this? If so how hard/easy was it and how did you go about it? I don't need a full tutorial (although that would be good :cheese: ) but anything by way of advice or anything would be a god send as I'm floundering at the moment

Regards
Boony
