Dont worry too much about the keywords - your list looks OK.
Make sure you have a good accurate short page description, which search engines may show when searches find your page. It should contain the most likely things people will search for, but also make sense.
Here is an example from my page (I hope my html code displays undecoded):
<meta name="description" content="Organisation of Measurement of Road Running Races in the UK, with info for runners, race organisers, and course measurers. The on line tutorial is useful for training measurers around the world">
Also choose a helpful title. For my site:
<title>UK Road Running Race Course Measurement</title>
You should do this for each page, but the most important one to get right is your main index page which should give the most important info, and then have all the links.
I would offer to do it for you and host it for free, but I know you will have some fun doing it yourself and I would not want to spoil that. Just get back to me if you have problems, and I will probably be able to solve them with basic html, since you will surely be able to upload html coded pages to the host. (You need nothing more than notepad to edit them. If you have an uploaded page which is wrong, give me the link and I will email you a fixed copy for you to upload.
BTW I have refrained from posting on the main new Jones counter thread which seems to have been drifting terribly off topic, but I did want to say that I want to purchase at least one from your first prototype run and carry out testing here in UK. We have an upcoming meeting where it would be great to report my own user experience as well as referring to all the good work being done over there. Just tell me how much money to send.
