tl;dr: Sourceforge's XMPP implementation is broken in such a way that prevents discovery of channels. Several people (myself included) have brought this to their attention, but they're refusing to fix it (because in fact they're not working on their gateways in any way).
Yet another reason not to use proprietary platforms, I guess :(
