That's good to know about using a different email address. I haven't sold yet on CL but my DIL buys and sells on it all the time and hasn't had any problems so far (fingers crossed).
I've been thinking about selling my nearly new Janome 6600 on CL but I'm not sure what kind of price I could get or how you go about it. I'll have to have my DIL advise me.
But then I'll probably dither around and end up keeping it anyway. I seem to have a sewing machine fetish. I think I have 11 machines!
