Good sign. I am sure Biln didn't just convert out of the goodness of her heart, or because she "lost a bet" ... it would be really encouraging and inspiring to see more insiders converting their options. A strong signal regarding their expectations and probably timing, since there is no real reason to do so with options unless they are expiring (and you aren't getting more reissued) or because "something" positive and value-oriented toward the shares seems imminent.
As always, waiting patiently for something to kick start trading and a pps climb again! ... seems there is a lot of "good" on the horizon, both short & long term potentially. glta
