As much as it pains me, I must admit defeat.  The free servers that some of us use for large parties will not show up on our Now Playing list.

Our links in the Broadcasters list still work so everyone can listen with just one click, even if the feed is not showing.

Such is the way with free stuff sometimes.  We'll just deal with it as best we can.  One solution is to run your own home server to trigger the Now Plaing list, and use the free server to handle the crowds.  Anyone that needs help with this can contact me.  Our FAQ on that is quite complete and I'm always available to assist.
