Even if your users don't want a full "audit trail" of activity, even if you aren't interested in doing a newsfeed, recording user actions in your application can be enormously useful. We'll look at a real-world implementation of recording that data, using a CodeIgniter-based application, and discuss three less-obvious use cases. Those are: Undo, Sync & Emails.
The meeting is going to be on Thursday, October 4th from 7-9pm at the Strongbox West coworking facility. If you're in the Atlanta area, you should definitely check this group out!
