For discussions, it would be great if people signed with their wiki username. See here for an example where single-letter usernames can be traced back to IPs, or can be confusing (my initial is also 'D', though I am not the 'D' in that discussion. Signing can be done by writing ~~~~. -- Supermike 02:00, 20 June 2011 (UTC)
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.
