We just wanted to reassure everyone who experienced issues when trying to access the site yesterday that it was never our intention to restrict permissions to only those who've signed up as contributors. Blogger changed a setting that apparently stopped people from being able to view posts, this has now been fixed and everyone should now have access again regardless of whether they are readers or invited contributors. Should you experience any further disruptions, now or in the future, please don't hesitate to contact us on sewretro at hotmail dot com.
Sorry for any worry caused and thanks to those who alerted us to the problem.
Anna and Tors
