Yes, we can/could make a wiki if we really wanted to. I have no idea what you would all want to make a wiki for but we can. I started one on the SC site and could move that over here, too, if you wanted. I was basicly trying to "dumb down" the lotro site to make things easier to find and add a few things. :P
If you want to help or start this, let me know. The editor is very easy to use.
