Nick,
Pictures on Flickr may well be found by people searching such resources for things Jowett, something Jack does a lot.
You must be logged on to search on JowettGallery and often pictures are not well annotated so difficult to find, but at least you know everything on there is Jowett related. Search facilities have been much discussed on this forum.
Jowett.net has been around for about 15 years. It is a back up site that can take over from Jowett.org. The two sites are in different continents and run by different hosting organisations. Any changes are replicated 4 times a day on a complex regime to minimize downtime in the event of failure or hacking attack, but it is not a non-stop system.
The sites swap over when there is a major upgrade as happened about 10 years ago to allow parallel running. Lack of support for things Internet from the JCC exec has slowed the swap over to the new site. But there is no reason you cannot simply use Jowett.net as your starting point. Any changes to Jowett.org are replicated on Jowett.net. Note that JowettGallery and JowettTalk both use Jowett.net as the primary site. this was because Jowett.org ran into performance issues 5 years ago and the primary site was swapped.
You should not need to have any written instructions for navigating the site(s) the left panel has the links to all the services, except the JowettInternetServices which are only on Jowett.net. The JIS are really not live yet as there has not been backing from the JCC exec even though more than half the membership use the Internet. They were promoted for booking on the Basingstoke Rally which some people used, but progress has slowed on introducing more facilities. I collected registers from some of the registrars so that I could add that facility.
The system is almost ready to go to implement the range of services but things do take effort in design, implementation and testing!
If you trawl back through the Jowetteers you will find that such explanations and help have been published. The last was introducing JIS which was done last year prior to start of Rally booking. It was on a separate pull out sheet for easy reference! But why not write to the Jowetteer yourself on how you see the system. It might be better from a different viewpoint.
By the way the system was explained at the AGM at length, much to the distain of the anti Internet lobby. I have put
the presentation in the Gallery.
