Log In Log

I am using the registered users plug-in written by Angsuman Chakraborty, Taragana. It works beautifully. My question is, is there a plug in that will keep a log of who logs in?

I know this is a feature offered by sitemeter for stats (as well as in the cpanel) but I’m looking for something that doesn’t necessarily show ISP info, but merely which user logged in when.

Is there a plug in like this that exists?
