Integrate Easyprofile avatar and user defined author info text into cjblog while keeping the cjblog author page (this is different from eg jomsocial integration > here you will be referred to the jomsocial user page thus losing the cjblog functionality)
You need to install the Jomsocial bridge provided by Easyprofile (for the avatar part)

you can see it in action here: www.lerendeleiders.nl/blogoverzicht
