Hi, Jonathan-

I agree with Cameron here, but I understand that you're trying to do 
anything that gets results, which is a pragmatic approach.

I spent some considerable time working on your issue yesterday, and will 
be sending out a detailed email in the next few days discussing how we 
should resolve this issue.
