Re: do I have to sign up for anything on the blind access group?
Your Groups.io account allows you to subscribe to any group hosted by groups.io.
For details on the blind technology group, which is what I think you're referring to, and how to subscribe and control your settings for it, sent an e-mail message to email@example.com
"Be Yourself" is the worst advice you can give to some people.
