Adding signatures in articles

edit

A reminder that signatures are NOT added in articles, as you did at this edit of New Jersey Institute of Technology. Signatures only belong on talk pages, not articles. A reminder that appropriate sources must also be included with edits. Alansohn (talk) 19:03, 14 April 2008 (UTC)Reply
