Just so you know - you should never sign your name after making an edit to an article. This is because any given article can have dozens, or even hundreds, of individual editors, and if everyone signed, then the article would quickly become an illegible mess of signatures. Information as to who made which edit is automatically tracked, and is available in the article history.

Conversely, you should always sign the messages you leave on article discussion pages or on user talk pages.

No harm done - this is just so you know. DS (talk) 17:55, 11 June 2009 (UTC)

Communication
People can check the article history and find out who made which edits when; they can then leave messages for you on your usertalk page. DS (talk) 04:04, 20 June 2009 (UTC)
