TwentyTen does not put rel=”author” links in the post byline so you need to get AuthorSure to add the links. TwentyTen does show author details on the author page so you just want AuthorSure to add the profile links beneath the bio.
This AuthorSure settings for TwentyTen are:
Author Post Settings: Can choose FootNote or AuthorBox
Author Page Settings: hide title, bio = none, set icons only
Advanced Settings: Set HookInstance =2
