Hi Robot, thank you for a brilliant site (or those behind it). I have 'gazed' from afar for too long, but now that I try to engage (sending some real, practical information)..... every time I hit send, I get returned to the 'you are not logged on' screen and I have literally spent hours expounding the dangers of 'battery banks' (and their advantages) to no avail.......What have I missed? What do I need to do to love the site and contribute what I can?
