I guess this means no such open source package (forum plus per-user blogs plus per-user photo galleries) exists. Another thing on my personal wish list would be a CMS that allows forum-like user comments to be attached to arbitrary or configurable interior pages on the website..............So, for instance, if my website displays a photo of a hotrod car users could make comments that appear in a pop-up mouse-over window. I might work on that one myself, as a plugin to my own favorite CMS. Putting all of this into a single, comprehensive package would be hot.
"Community" is what the web is all about. People want to go to places (like this forum, Facebook, Google+ etc) where there is something new each day, and where they themselves can get noticed by saying something that everybody else reads. Forums are great. But forums are last century now. Forums need to be more like subdivisions where people build a house, plant photos, mow the grass and plant their digital gardens.
