You guys have been a huge help. I'm sorry it's taking me so long to respond to everybody, but my move schedule got changed and I've been nuts trying to move to a new place! My computer is on the floor at the old place, so that tells you how topsy-turvy everything has been! busily, Alex _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
