not sure how users use communities

I set up communities and then registered as a user (no link yet but it is at normal wp-signup.php btw; love the no email required plugin). Once I log in, all I can see is my profile, dashboard and avatar link.

Not sure what users are supposed to do to get to the wiki, or new or all the other features of community.

Pretty new to working with networks and working with your plugins. Don't see any reference in the docs for how to get users using community.

Thanks for any assist or direction you can give me.
