It never concerned me... I tried looking myself up using a number of "search sites" and...hee hee.... I can't find me (nor could I find my DH). So, if some whacked-out DISer wants to hunt me down, I'll know who it is because I keep track of who has my address. And I'll thank her again for the lovely gift she sent me from the recipe exchange! But seriously, I'm not worried about giving out my address via exchanges and such... there's a certain point where you just have to "let go and let God..." so to speak. It's more dangerous for me to get in my truck and drive back and forth to work than it is to participate in exchanges on the DIS.
