I just searched your posting history to see if there's more information re. your current query - sometimes that happens when people post. Anyway, the second query of yours that I checked had four replies - and you also had apparently not read them. You might want to visit your own "posting history" list and systematically go through, collect the information kindly gathered for you, and thank your contributors. Sometimes Genforum's message system fails to notify posters about replies. Don't know why, but I've had it happen to me, so thought you'd appreciate a heads up. And you'll probably have to revisit the forum on your own initiative to physically look for replies - if you're not getting notifications in your email from Genforum. Arghh. But worth it - the forum is a great resource and volunteers here are invaluabble! Cheers!
