User:Nsk92

I am is interested in world history; in privacy rights and privacy protections, especially in relation to internet; in science and mathematics; in immigration issues; and in science fiction.

I am a supporter of the Electronic Frontier Foundation.

I have a secondary account, User:Kinoq, that I used briefly in November 2009 berfore I managed to recover my lost password for this account.

On Wikipedia, when I am referred to in the third person, I prefer to be referred to as they.

Wikiprojects I am following

• Wikipedia:WikiProject Mathematics

In March 2008 I made a proposal[1] to strengthen WMF's privacy policy by including a notification provision for the cases where identifying info of Wikipedia users is sought by third-party subpoenas. The proposal was later adopted by the WMF Board of Trustees, Wikipedia:Village pump (policy)/Archive 46#Update in privacy policy, and is now a part of the WMF privacy policy[2][3].
