I'm in the middle of doing a simple Blackboard/Message board system for use in work. It's pretty much done apart from the final part that the bosses want done which involves creating a log file stating who read the messages including date and time. The date and time is easy enough but I'm not sure how to identify who's read the message. The only way that I can think of is to use everyones WinNT Logon, but I'm not quite sure how to do this.

So basically what I want to do is creat a text log file in the following format:

"(User) read the message at (Time)(date)"

Any help or suggestions on how I can do this would be appreciated.


Cheers
