Well, drat. Thanks Burt but I don't think I have the ability to do what you describe. However, I'll download that contribution and see if I tinker around anyway. Where is this "date-default_timezone_set"?
OK, you add-on developers, get cracking! I need this by the end of the month! :)
If nothing else I'll just remove the menu items manually at the end of each week. But I hate to rely on remembering to do that!
