Attribute Mapping using Java Script

I'm active visitor and answerer of several forums about Microsoft Dynamics CRM. I have seen a lot questions about mappings - how does it work. Mapping works only once - when new child record opened from parent record and when user just fills parent record lookup - of course mapping doesn't work. I've decided to fix this issue.

CRM Usage Report

One of customer wanted to have the possibility to see who and when was working in CRM. I knew that MVP David Jennaway had created such solution based on IIS's logs. No matter how I tried - I failed to implement it. Logs weren't written to log database. Also this approach doesn't work in IFD deployment scenario.

So I left this idea and begun develop own solution.
