I was wondering if the Discussion extension uses avatars or if it can integrate avatars from other extensions, such as easyprofile?
If not how hard would it be to integrate it, and how much would it cost if it does have to be customized to allow this function?
For the moment we don't have any plans to integrate avatars from another component.
I will definitely consider this for future releases, supporting Jomsocial and Easysocial avatars.
PS. I am moving this question to the Features Request topic.
