From the webmaster

One of my main aims is to make this web site a comprehensive source of information for Cleveland-based orienteers.  In particular, you should be able to find information (or links to information) about all the events that are likely to be of interest to orienteers living in the Cleveland area.  This includes our own CLOK events, of course, but it also includes (a) all other events within reasonable traveling distance and (b) major events -- like the JK, the Scottish 6-Days, etc. -- that are likely to be of interest to CLOK members.  With this in mind, if you find anything missing from the site then please let me know.

I set up RouteGadget in October 2006, so competitors at CLOK events can now view the course maps, enter their routes, view other competitors' routes and watch animations showing how they and their competitors progressed around the course.

If you have any views on which developments should be given priority, or if you have any other ideas for improvements to the web site, then please contact me.

Also, if you find any broken links or errors then please let me know.
