Ha Ha!  Once we have you on the inside we like to lock you in!

But seriously, it is a rather annoying quirk that I have built into the site. I could easily not find a simple way of providing a log out button within the security approach I have adopted. In order to log-out you have to hit the ‘Logout’ menu item at the top-right of the screen and then additionally hit the ‘Logout’ link which appears on the right had side of the following screen.

Cumbersome. Sorry.
I put it to the bottom of the ‘To-Do’ pile but now you have mentioned it I will look at improving this.

And thank you very much for the feedback – its good to hear about people’s experiences with the site, good and bad.
