Hi, I talked with Don Jagoda managers about this. This said the mail-in entry are scanned and converted to a digital entry. Each entry is assigned a number or code at that point. This seems very fair and honest. There might a different method by other administrators but I think it would be close to what they use.
If a sweep is both mail-in and online, do they accept both? I mean, I can never figure this out. I've read in the rules and I can't see where you can't do both......usually they only let you enter online once a day, but then unlimited mail-ins. Just wondering.
