OK the guy wrote back and it looks likely that we can have some. How
many? 900 is an awful lot...
Mitch: 200?
Daniela: how many would you use?
Michael: how many for you?
anyone else have ideas?
I'd like to get back to him later tonight, or tomorrow at the latest,
since I took so long the first time around, and ideally I have a number
to ask about.
Reasons why we should ask for all of them are also acceptable!
