The Octave website has been rewritten, but with any luck, except for the members' page, no-one will have noticed. The site is now delivered from a Content Management System (CMS) called Perch. One of the features of the new site is that everyone can have their own login and password to the Members' page instead of a group login that changes every year. To get your login go to the http://octavechoir.co.uk/members/ page and click on Register.
After you register you won't be able to use your new login until it has been approved, this only take an hour or two depending on when I see the email notification I get from the system. If you've not heard in a day or two then raise a ticket on this system.
If you have registered but still can't get in then check that you are entering the same email address that you registered with and that your CAPS LOCK key is not accidentally on. If you've forgotten your password click on the 'Forgotten Password' link on the login page.
I can set passwords if you get really stuck but I can't read existing ones.
