I thoroughly agree with all the points made so 
far, and I think that they include better 
suggestions than the one I just e-mailed you 
(couldn't post it here because it's a little 
long-winded).

But if you think certain problem bidders are not 
totally blind to reason and you still want to 
get some of the money that you are entitled to, 
perhaps the compromise I e-mailed may work.  No 
guarantees, though.

Hope it helps.
