andrei, I am guessing that Vista and Caremart have been shut down or will soon be. They have created little value over the past two years and IMO most likely will not be a part of any Reverse Merger should that occur.
Please remember I am speculating here. No news from the company this quarter, that tells me they are looking at their options. "I'm On Air" was a hot topic. IMO, the only reason it has gotten quiet is that they ran of cash. I believe a 10K is also due before month end. Hopefully we will see this filing however bad it may be.
Just my opinion.
