KRY was delisted from NYSE/TSX/Venture in 2012, and from OTC by the end of April 2013.

(You can even see a chart showing 0.065 as the close... ah memories)

Many brokers simply adjusted the CRYFQ holdings total to 0.00, but even if they didn't, shareholders couldn't trade, so eventually the broker would've clued them in that these were essentially worth zero. Some reported to have written it off as a tax loss, and it would likely not be far reaching to assume that many simply forgot about it altogether.

The fact that we managed to get 218 opt-ins (30% of outstanding commons) to date from word of mouth alone is IMHO an impressive feat in itself as we do not even have this many users posting on this very board, which if I am correct is the only active shareholder forum.

So let's not downplay this number or make silly assumptions that 70% of shareholders were somehow against the opt-in. If management were kind enough to provide Gowlings with the full list of shareholders, I bet my life we would've ended up with a much larger number of opt-ins by now.
