Hello, 152.37.102.192! 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 Wikivoyage:Help, or post a message in the travellers' pub.
By the way, have you considered creating an account here? While you can absolutely keep contributing as an anonymous user, it promises a bunch of benefits, and no obligations.
Your edit to the London article looked reasonable to me, but I haven't been to London since 2010, so I don't know whether it's accurate or not, but what you need to know is that the words you edited out had been decided upon by a consensus on the Talk:London page, so in that circumstance, a substantive change like the one you made requires your restarting discussion on that talk page and convincing a consensus that actually, you are right. So please restart the discussion. Thanks!
Best,
This is the discussion page for an anonymous user who has not created an account yet, or who does not use it. We therefore have to use the numerical IP address to identify them. Such an IP address can be shared by several users. If you are an anonymous user and feel that irrelevant comments have been directed at you, please create an account or log in to avoid future confusion with other anonymous users.
