Currently one is unable to start a Query. There is a raw version of Server::handleUserQuery() but there is still work to be done.
As soon as Sput has finished BR #41 I'll implement the handling of user queries.
If there is objection to my suggestion regarding BR #37 I'm going to treat /msg and /query commands according to my last Note.
We should at least make /query an alias for /msg before the release; the fact that it does not do anything yet tends to confuse people :)
And btw, #41 has been closed long ago ;)
/query now opens always a buffer and stores you're message.
/msg just sends the message to the target without storing it or opening a buffer.
