Better than Rufus' response - which was no response at all. Seriously, if a REAL publicly traded company were in the same position - and the letter was a fake - they would be bordering on gross negligence for not denying it publicly.
This is real money, invested by real people. This is not some cute little game. Issues like that C&D are EXTREMELY serious. No response from the company means it's real.
A phone call to Canady, which all of you seem quite nervous about making, would be even better proof.
