I actually might view the lack of response to your requests as a positive. I gave up trying to contact IR people years ago not only because they are typically clueless, but more importantly the responses are very generic and scripted.
IM proceeding with caution, although I gotta admitt I never expected this west nile situation to blow up as it did. CRXL is mighty risky since its not very liquid but it sure could take ou $6 in a heartbeat if people pick up the speculating again.
Thanks for your response and all the best! Rough market to start the week.
