Hi, I have set up a website to do a blog on an upcoming trip we are doing with school. I am wanting to allow the parents and colleagues at work to follow us on our trip. In the past teachers have sent an email with a website link to all the school and then we just click on it and we can follow the trip. How do I go about doing the same thing? I tried doing it as an invite but when the person went to accept a message came up saying the invite is not valid. What am I doing wrong?
