It is a sad day really. because of surfeit of spammers and some spam review posts we have reluctantly decided and implemented a login requirement. From now on if any visitor desires to leave a comment it will be necessary to log on first.
To all our other visitors I must apologise for this apparently unneccesary barrier. The logon facility is on the sidebar which can be seen from every page.
This then pulls up another window where you can enter a user name and password.
