CMP 1911's

[Orlando]

Does it matter what your number is? When they get to you then you will be notified. Numbers are being assigned to all 19000 orders. When yours comes up you will be notified. If your number is above the allotment of the years 1911's you be in line for next year

OK CMP, here you go.
This Java code will read in a file of customers emails, assign randomly, numbers starting at 1000, write the results to a CSV like that can be read by a spreadsheet, and email these out to everyone.

Thank you.

[TheRealJimDavis]

They did. All the packets have numbers. When they get to the packet, in that numerical order, they check it, then send out the email telling you what your number is and if the packet is good to go or not. Or at least that’s the impression I got reading their forum from the admins.

[TheRealJimDavis]

It’s not that your packet doesn’t have a number yet. It’s that they haven’t gotten to that number of checking packets yet.

And apparently the whole lottery is at fault and they should have been first.
