Yup I noticed a few more Orphans than normal.
I usually send them this when I see a new user enter a orphan.

"Hi & welcome to the word of money tracking!
It appears the marked bill that you entered was originally
a bill that someone forgot to enter-in (an orphan).
So unfortunately the history starts with your entry.
Or you just came across this site & decided to give it a try.
You could enter a few of your own bills if you want to.
Make sure you enter all marked bills you come across!
Its fun to see where you money has been.
Any questions just "Private Message" me.
Have fun tracking.
