How do suggested edits work?
I've encountered several questions that are tagged to broadly, e.g. this question is specific to sql-server, maybe even to sql-server 2008 yet it is tagged just "sql".
Other questions on this site suggest the original author to edit his/her own question. But I can't find how to do this for another user's question. Is this a privilege for which I still have to earn sufficient reputation?
What is the recommended way to add a tag to such a question?
