10 days is a short time period.
If someone is on a 2 week holiday, and without access to the internet so they can log, it could be 14+ days before they start logging caches and TB's.
There is still hope!
I hope it does show up but who doesn't have access to the internet for 10 days in this day and age? I'm in the Portland Metro Area also known as the "Silicon Forest", the internet is everywhere.
