1) How do I integrate these three into a single login? The information I'm finding on the internet seems old. Do I need to download a plugin or edit some settings?
2) I have the Wiki on my site at http://www.absolutesl.com/wiki/english-as-a-second-language-wiki/ now... but how do I create an index for the wiki? Do I have to create subwikis in order to cover multiple topics?
