The barnes Trainer is a very new company, although the invention is a few year's old. Not everyone knows a lot about computers and forums and posts, etc. We fall into that category. We only recently realized that the product was being discussed on line. We wish we had known sooner. But, the same day that we became aware of it, we posted a message to give people a chance to ask questions and also to find out another side to the discussion. Maybe we still need advice on the best way to enter an ongoing conversation on these message boards.
