for all we know Jim is travelling to Mexico to work on his other company and not UC. His focus may now be on the other company and not UC. I would interpret the silence as re-directed attention on other interests. I have seen this before and even been through this before with other companies. It is called Jim's "New Shiny Object"...
OK, I will apologize in advance for the negative sentiments I am now feeling, however, I am still long and strong... can't afford a loss on UC...
