You don't have to registered as a WikiUser to be able to edit a page. But it's highly recommended that you do create an user account. So we can see who makes changes to existing pages and who creates new pages. And you can promote your site from your personal page.

It's possible that anonymous editing of pages will be disabled, that way the amount of unwanted editting could be reduced. I can decide to do so whenever it is necesary. So please create an account.
