Ta-da! Tracing the Tribe readers have indicated it is difficult to figure out how to add comments to a post.
It may have taken some time, but as of today it is now much easier.
Under each post, you'll see three lines of little items. The second line gives the number of comments already made and now says "Add your comments here!"
Just click on that item, and you'll be able to see past comments and leave a new one.
I do hope this improvement means hundreds of additional readers will now be leaving comments, and I look forward to reading them!
