There is no way to disable the "Network" feature in Confluence 3.0. Some customers are concerned about the privacy implications of easily being able to see what changes people have recently done on the wiki.
There is also no way to disable the "Follow" feature in Confluence 3.0. Some customers are concerned about potential difficulties with employees following or not following each other.
Allowing customers to disable these features when deemed unnecessary or harmful would be a great advantage.
Note that the Status feature in Confluence 3.0 can be disabled, as it's probably not useful on public web sites.
