I know it's not my question... but just thought I'd give Pleiades a big rap for the good work he does in replying in detail to everyone's queries no matter how big or small an issue they have. Maybe I'm feeling sentimental at this time of year, or else it has occurred to me that you're always chiming in with invaluable and timely advice for us less experienced punters... but it is great to have you as such a resource. So thanks Pleiades!
