Hi Tom

In case it can help, have a look at this old thread:

Log in or log on?

Also, I remember that there was another discussion exactly on the topic, but I've failed to find it now :(
That search engine... you know...

In my today's view, 'log in' is a bit more general, whereas when you 'log on', you are going to do something.
