After playing around with your script I noticed that the access logs are visible to everyone that has an account. IMO it would make better since to put this information on the system page or similiar due to the fact that the access log contains IP addresses of each user and who the user is.
Other than that, this is one of the best news scripts that I have found. Keep up the good work.
At the time I posted, I was using a commenter access level and was able to see 3 different accounts access. Since then I have not seen it repeated. I am guessing it was a fluke in the cache in my web browser.
