If you don't already have a Google account, you can create one (free) here. Note that the account creation screen defaults to having you create a new Gmail account, but you can click on "Use my current email address instead" which creates a new Google account associated with your existing email address.
If you want to subscribe to Sorehand but also want to not have a
Google account
(which means you will receive emails but won't be able to use the Web interface to the
Sorehand forum), please send an email to
sorehand+managers@googlegroups.com with a Subject Line
like "Sorehand Subscribe Request" from the email address you wish to subscribe.
If you have a Google account, go to https://groups.google.com/a/routinemiracles.com/forum/#!forum/sharchive and click on "Ask to join group". (If you're not offered "Ask to join group" but are offered "For access, try logging in" click that to log in to Google, after which you should see "Ask to join group").
If you do not have a Google account, you will need one to see ShArchive. You can create one (free) here. Note that the account creation dialog defaults to having you create a new Gmail account, but you can click on "I prefer to use my current email address" which creates a new Google account associated with your existing email address.
Note: The archive as it stands now is static; posts after April 5 2016 now only appear on Sorehand itself. Some further software development is planned to make ShArchive keep itself current with new posts; we are hopeful it will occur.
