::Editors who have not logged in may be identified by network IP address. Depending on one's connection, this IP address may be traceable to a large Internet service provider or more specifically to a school, place of business or home. It may be possible to use this information in combination with other information, including editing style and preferences, to identify an author completely.
=====Discussions=====http::On wiki discussion pages:::Any editable page can theoretically be the location of a discussion. In general, discussions on Foundation projects occur on user talk pages (associated with particular users), on article talk pages (associated with particular articles) or in pages specially designated to function as forums (//e.g., the Village Pump). Privacy expectations apply to discussion pages in the same way as they do elsewhere.::Via email:::Users are not required to list an email address when registering. Users who provide a valid email address can enable other logged-in users to send email to them through the wiki. When receiving an email from other users through this system, one's email address is not revealed to them. When choosing to send an email to other users, one's email is displayed as the sender.::The email address put into one's user preferences may be used by the Foundation for communication. Users whose accounts do not have a valid email address will not be able to reset their password if it is lost. In such a situation, however, users may be able to contact one of the Wikimedia server administrators to enter a new e-mail address. A user can remove the account's email address from his preferences at any time to prevent it from being used. Private correspondence between users may be saved at those users' discretion and is not subject to Wikimedia Foundation policy.::On mailing lists:::The email addresses used to subscribe and post to Project mailing lists are exposed to other subscribers. The list archives of most such mailing lists are public, and searches of public archives may be performed on the Web. Subscribers' addresses may also be quoted in other users' messages. These email addresses and any messages sent to a mailing list may be archived and may remain available to the public permanently.::Via OTRS:::Some e-mail addresses (such as info-en at wikimedia dot org) forward mail to a team of volunteers trusted by the Foundation to use a ticket system, such as OTRS, to respond. Mail sent to this system is not publicly visible, but volunteers selected by the Foundation will have access to it. The ticket system team may discuss the contents of received mail with other contributors in order to respond effectively. Mail to private addresses of members of Board of Trustees and to staff of the Foundation may also be forwarded to the OTRS team. These messages and e-mail addresses may be saved by members of the OTRS team and any email service they use, and may remain available to them.::On IRC:::IRC channels are not officially part of the Wikimedia Foundation and are not operated on Wikimedia controlled servers. The IP address of users who chat over such a service may be exposed to other participants. IRC users' privacy on each channel can only be protected according to the policies of the respective service and channel. Different channels have different policies on whether logs may be publishedkamagralek24.pl
