How do the bloggers edit their bio

One of my bloggers just asked how to edit his bio and I am having a hard time finding it. I have not found it for myself either. I must be missing something basic.

Here is a page where you can see our bloggers and their bios:

Can you tell me where a blogger is to go to edit their bio?

I also use EasySocial on this site and maybe that is complicating things because we use EasySocial for the login management?

Thanks for a pointer in the right direction.
