EmForge designed to be not only Project Collaboration platform, but we have a plans to make it a Social Network for developers. We are not going to implement own new Social network, but want to integrate with many already existed Social Services widelly used by developers.

We already simplified login with using Google, Yahoo (and any OpenID in general) account. Now, we providing integration with Gravatar - service kept user avatars in one place.

Now, if you have avatar there - no need to define new in EmForge - EmForge will just reuse it. Of Course you can change it to some EmForge-Specific (if you want).

It is only first steps, many more social features planned in the nearest feature, first of all integration with Google Services, LinkedIn, Friends Connect.
