I like that.
This is getting more complicated. However a 5 year map marked with the queen color would be very, very nice.
i.e. 4 years of history with the current year's activity.
And (yeah I know, that makes the queries more complex) check-boxes to select which years are displayed.
I could take a crack at it if you could let me know where you got the current map. I used to make lots of changes to YABBSE and the SMF code base is much cleaner & easier.
