Also, to answer on your questions:
 * Forums are a communication feature. In Community Central, threads in here are usually for technical purposes, questions about features and some other sort of general discussion. In other wikis, they usually use them for discussing about the wiki's topic. They are soon going to be replaced by Discussions. You can learn more about the forums here.
 * Kudos are like upvotes to a specific post, to prove your appreciation or agreement to that post.
 * The "Live! Chat" feature is basically a chatroom, where you are able to instantaneously communicate with others. This is enabled only on certain wikis, because it is a Wiki Feature. You can learn more about the chat here.
