I saw the following being written as wanted from a new newgnr site:
Implementing open source social networking software that has forum capability like ELGG. Customizing the theme where it fits in with the rest of the site. It will allow members to have their own blogs, share content, have tradition forum use, and communicate just like facebook or like GNR's Night Train . It will allow users to join via their facebook accounts (making it easier to join in) and share their own, others, and site content to other social networking site creating more exposure for this site. It can be moderated just like it is right now too. Plus it will allow users to block people and make things easier for moderating. It would also have video section for new videos and possibly user videos for GNR related topics or maybe even streaming from other video sites.
The current software used by newgnr might not have these features, but other GN'R forums do. E.g., A4D allows users to have their own blogs, integrated chat, join via Facebook account, and sharing content to social media as well as friends list that allows blocking other users.
