Update - regarding Comment thread #1530 - Discogs - unable to login via their site's identification system but ... they have stated that their security ID system generated an error, which they said was to blame, but even now I cannot login, so I am still having to wait and see if this website can be used directly to login with Wayfarer. I am in contact with their support desk, but it is not so inspiring at the moment!

If I manage to get past the login screen (legitimately) then I will update this thread. Just in case anyone is interested.
