During the brief period before the admin shut down the blogging feature of UB5, I was able to explore some of its features. It looked pretty cool. It basically allows members to create and moderate their own private sub-forums. It could be used to form a private space for invited members to share insider info about sports. It could be used for creative writers to privately workshop their ideas. It could be used by cliques of friends to gossip about others.
Anyhow, it is just some food for thought. I was just goofing around with the feature, but I'm sure that others could put it to real good use.
