Notice from Rubicon' management to its shareholders:
"It has been brought to our attention that certain responses issued from our Investor Relations Department to emailed questions have appeared on various bulletin boards. We have amended our policy, and accordingly will not respond to emailed questions."
They'll still accept phone calls but nobody will be available to answer your questions. If you don't like this new policy, sell your shares at a loss, suck it up and move on. IMO the company couldn't care less.
