Moderation in Connections 4.5 is an awesome feature, but may be pretty cumbersome. If you decide to moderate everything before it get published (ex-ante), you will enforce an strict rule over you social network. If you moderate after publishing (ex-post) ,you are basically relying on good will of other users flagging content around your organization.
IBM Connections not offers you the very powerful role of Global Admin. It's a J2EE role, it is present both on Communities and Search (and other features too), but now let's focus on these two features.
So, a global admin can do everything on every community: great stuff, but how he gets to know a community exists? With the basic community ui you have access to
1) Communities you own
2) Communities you are a member of
3) Public communities
And the global admin role technically is neither of three. That's why the global admin role is also on search application, where he can see everything. So global admin could simply go to the search panel and looks for all communities? Well, the problem is search UI by default will not accept a blank search argument. So you have to search for a letter, or something. So you won't have access to every community! How you can do this without using wsadmin script? Very simply using the atom feed!
This will show you every community you are entitled to see! So, if you are global admin, it will allow you to modify every community in your Connections!
