At risk of adding another piece of junk mail to your box, I would like to
apologies for the multiple post.

It was the fault of the web client I was using for the post, a periodic
refresh of the inbox was actually a post of the original message, not an
intentional barrage of email.

Thanks for the feedback.

I'll discontinue its use.

How many times are you going to send this same message to the lsit? 
I've counted 6 now...
