I totally agree with you. I don't think it's a scam. Not saying the company will be successful or unsuccessful. The company appears to have a legitimate product that needs to be enhanced or marketed better.
One month of silence is really not so bad. Let's give them a little longer to issue another news release. The stock will probably rise one the company starts updating us again.
I am invested in another company that is tardy with their news releases. These companies would not be in the OTC market if they released news at regular intervals.
