As one who has left several times, sometimes with notice and sometimes not, I understand, Dave. If you feel like you can handle being back, you'll be part of an exclsuiive club of those who share that history-- and please, PM any time even if it's just to strengthen your resolve. And thanks for the goodbye note-- I know some folks think that's bad form but I think it's helpful to know straightforwardly from the one who's leaving speaking for themselves!
