Some of us still stumble about on this platform, so I hope this might make it a little easier for non-Blogger or new-Blogger bloggers.
To change or add to your bio this is how:
1. go to Bookartobject
2. click "new post"
3. click "edit pages"
4. click "contributors"
5. click "edit"
You'll find you names alphabetically by surname.
Then just write what you want the world to know; give it a label if you like,eg - bio update.Click publish. Have lunch. Take well-earned nap!
