Well, I've still got to do some background coding for it (and I have a free weekend for it) but I do have talesofazeroth.co.uk and some php/mysql hosting, so can set up a simple site for story submission and editing. It'll be easier then messing with a complicated wiki software.
Note: trying to access it right now will fail as I've got to get the address connected to the server first.
Additional Note: adding stories will be done similar to how forum posts work. (I may get a wysiwyg editor working at some point).
Why am I still editing: The site's layout/template will be the same as http://www.geocities.com/acaeris/islandofblue.html except I'll change the title to "Tales of Azeroth: Stories by the members of Rhyme and Punishment"
