There a quite few people on the PRGN google finance discussion boards. The majority are quite polite and provide each other with great information on the company and also the industry in general. However stock discussion boards are littered with trolls that post just to get a rise out of people or some cases post in an attempt to scare people into selling their positions or pumping up penny stocks. 

So a couple of us on the board have setup a google group that we hope will be a great place to carry on our discussion and have better tools to deal with unfriendly posters. You have to request an invitation to join if you are interested. We are doing this just as a small barrier to entry and have no plans to make the group exclusive in any way shape or form.
