I believe matju had them shoot out the leftmost inlet of the abstraction, with the assumption that the user would have a [route] sitting there to parse them. Another idea would be to retrieve them from an introspection object like [canvasinfo] (and maybe have another object which splits that into a sequence of messages).<br><br>-Jonathan<br><div style="display: block;" id="yiv2060659032yui_3_16_0_7_1414103441072_7" class="yiv2060659032yahoo_quoted"> <div
