Some users are having problems accepting reader and author invitations on the new version of Blogger in beta, and see an error message when they log in to accept. While we sort this out, the workaround is to send the invitation to a different e-mail address. The invitee may still accept the invitation with whichever Google Account he or she wishes. Updated, 11/20: This is now resolved.

If a user has a Google Account but hasn’t signed up for Blogger with it, and they get invited to a blog, they may not be able to post to it. The fix for this is to go to beta.blogger.com and explicitly sign up for Blogger from there. Update (9/26): This has been fixed. The workaround is no longer necessary; new authors will be prompted to sign up for Blogger when they accept the invitation.
