I am coming up on my 13th year on CMT in a few months.

In the first six years I entered about 10,000 bills 96% stamped, and got 315 hits.
In the last 7 years I entered a little over a few thousand more bills only about 2% stamped, and only got 11 hits.

This "New Path" is partly because of the new plastic bills are a pain to mark, and also because of burn-out, and the fun kinda just died down for me.
Rather than just totally packing it in, I just enter a stealth bill most days, play the monthly hit contests, and keep in touch by reading the messages...
