Creating a user name is free and takes only a minute and it gives you greater anonymity if that is your wish. In addition, it is easier for other contributors to ask you questions and help you.
Of course, we hope you continue to make contributions, even if not logged in.
If you are new to Wikia or wikis in general, please visit the Community portal for an outline of some of the main parts of the site and links to pages that show you how to edit.
Discussion of any aspect of the site, and enquiries, can be made at the Forum or on the "discussion" page associated with each article. Please sign and date your contributions there, so that readers know "who to talk to" and whether your message is probably still of current interest.
