Match reports are articles about matches that can be created on the front page of the web site.
Registered users may therefore have access to sensitive areas of inter-action where casual website users should not be as they could change results, etc, and cause mayhem.
Once you have registered yourself, the site administrator (the Secretary) will receive a notice that you have registered. The administrator will then decide if the registration is valid and can be accepted. He will also determine what user level will be allocated.
If you are allocated the level of Author you can create an article but not publish it. This is normal procedure so that the administrator can vet all articles and make them suitable for publication.
