Hi Tomasz,

I hadn't considered that ... but actually that would not be too much of a
restriction (only works with a connection to the hub).

That looks like an excellent idea.
I will look into the details some more.

Thanks!

Maybe you could do with a autojoin-chatroom feature of a client?<br>
Most popular Jabber clients have it implemented.<br>
