Thank you all for your wonderful feedback.
I'm slow to reply because I only recently figured out how to get the sundial mailing list off the spam list. Gmail mad 'improvements' to their spam filter and they believed the SML to be spam. However it did not visually put it on the spam list so it would not give me an option to remove them from the spam list. I got them off by adding them to 'my contacts' As far as the testimonies, Only half of them are genuine. To be honest I forgot about them and regret not taking the false ones down. I put them up as I was laying out my webpage. I have taken off the false ones. Most all teachers that see my sundial like it. However they don't have control over what the school sets aside for their curriculum or what they have time for. I try to explain that It does not need to be constructed by the children. However, I sound like a telemarketer. I'm a draftsman. I feel like a fish out of water when it comes to selling. I'm looking for educational marketing companies that will sell on commission. If anybody knows of any please contact me. My efforts so far have been to approach schools directly in an attempt to give away my sundials. I knew my website needs photos of children. I'm a terrible salesman and the results discouraging. About year ago, (shortly after I had the w3c errors fixed) I started running into financial hardship and stopped spending on things like SEO. I have a better google ranking now that I made my website mobile phone friendly but I haven't spent anything on SEO. I would welcome any help on SEO. My website still sometimes has a problem when viewed from Internet Explorer I have build a small scale sloping sundial. After a few preliminary test trials, I'm about 80% certain that my sloping sundial will work. I need to talk to a surveyor to work out how to communicate/describe the slope and how to tell people how they can construct it off my dimensions. I will design a sloping sundial at no cost Donald Cheers Donald Christensen 0423 102 090 www.sundialsforlearning.com On Sun, Jul 28, 2013 at 12:27 AM, John Carmichael <jlcarmich...@comcast.net>wrote: > A simple method of laying out a human analemmatic has just occurred to me. > > 1.
