Regarding not getting a response from Leo, guys please understand he is a very busy man, and sometimes he either does not have the time to answer every email, or for his own reasons may choose not to answer as maybe the questions being asked are not things he can answer.
This notion that he only replies to a few select people is not true, he just has to limit his email communications for the above reasons.
Heck, when the interview was first pitched to him, it was weeks and I didnt hear anything back. Finally, after a few unanswered emails I wrote him a note saying I understood he was very busy and I appreciated that he had intended to do the interview, but I also understood that he didnt have the chance. Only then did I get a quick response apologizing as he was "buried in Prurisol Trial paperwork", and shortly after that he finally made hte time to answer my questions. (on the weekend, by the way)
He is only one man, and working very, very hard to meet all the goals and timelines set forth by the company, on top of making sure financial filings are done, deals are negotiated, bills are paid, and clinical trials are progressing smoothly.
That is a hell of a lot of work for him and Dr Menon, so I cut these guys a whole lot of slack, and am very thankful for their openness and communication with all things considered.
So cheer up and be glad we don't have NNVC-type management response. LoL.
