Multi user application

[eluser]arthurhanlon[/eluser]
Hi there,

I stumbled across Codeigniter a while back and am absolutely loving it so far. I am in the middle of re-writing one of our smaller applications simply because I cannot follow the code written by the previous developer and have decided that Codeigniter is the best choice.

It's an application that will be used by multiple users at the same time though and I am unsure as to how it will fair once it's live as many of my applications to date have been used only by myself.

I was wondering if any of you could lend some advice with regards to developing a mutli user app with Codeigniter? How are you guys doing it and what things should I be aware of?

Thanks in advance guys,
Arthur
