And here is the workaround!

// Auto-signs each post $(".replyButton").click(function(e) {   var sign = " "+ ("~".repeat(3));    var editframe = $("#cke_contents_WikiaEditor-0 iframe");    var inner = editframe.contents.find("#bodyContent");    inner.html(inner.html+sign); }); This will now use your real signature, as defined in your settings.
