1. Go to Customize tab and then Settings. Under Comments, either allow Anyone to comment or Only Registered Users. If you do the latter, you will have to add all of us by email addresses (see picture 1).

Anyone: anybody in the whole wide world can leave comments
2. Under Permissions, allow anyone to view the blog.

Go into each blog, read the posts, comment on at least one posting in each, and add yourself as a Follower by clicking the Follow button in each.
