I will tell you this, their "spam" like
emails and fanatic names for customers is
what prompted me to create an email JUST for
x10. to everyone you might want to consider
something similar by making an email (if you
have access and ability within a domain) just
for x10, something like x10@somesite.com or
whatever.
I did this and was very pleased that i was
able to delete the email AFTER the sale didnt
go well. hope this info helps someone
