XML-RPC story creation

[Manila-Newbies@userland.com]

I create new messages via RPC using the following:

betty.rpc.client ("my.server.site", "80", "manila.message.create", @params)

I would like to confirm that when a new message is created by XML-RPC the only callback available is the notification callback at

config.mainResponder.callbacks.rpcNewMessage

Is there another way to create manila stories via RPC?

cheers,
Christopher
