Preview & Edit Summary
I was following your attempt at inputting a reference on Portfolio optimization and saw you having trouble doing it, which created a long list of intermediary edits. FOr future use, if you can use the preview button to check if something works before submitting, it will reduce the 'spam' and all the unecessary intermediary edits in-between. Also, if you can use the edit summary to let people know what your edit is about, that would be great too. - Happysailor  (Talk) 10:56, 6 January 2013 (UTC)
