Hello, Cameronlund! Welcome to Wikivoyage.
To help get you started contributing, we've created a tips for new contributors page, full of helpful links about policies and guidelines and style, as well as some important information on copyleft and basic stuff like how to edit a page. If you need help, check out Help, or post a message in the travellers' pub. If you are familiar with Wikipedia, take a look over some of the differences here.

editHello, Cameronlund. You may be well-justified in adding a listing or information about this site to the London guide, although it would seem to violate Wikivoyage's guidelines on what can and can't be linked. However, it's important not to have edit wars. So please post your argument in favor of listing this site to Talk:London and see whether a consensus can be reached that the site is so important to travellers that an apparent exception to the normal external links policy should be made.
I think people will give you a fair hearing.
All the best,
