Is there a quick way of going back in my log to a particular date or event that may have been several years ago?
Yes. Scroll back one week, then look at the URL, which will have a date in it. Change that date to the one you want.
Thanks - why didn't I think of that!
You can also view "all weeks", scroll down, and click on the week in question.
Count the number of rings to determine how old the log is.
I'm not looking that closely at Simmo.
