The free radioboss.fm will operate till at least October 01, 2013. But after that no free accounts will be available (there will be free trial accounts for 2 listeners).
The new version of radioboss.fm is better:
* Higher quality of service: as you see the free accounts sometimes fail to work (servers are down, slow, etc). We start to charge for it because it's hard to maintain high quality level for free - to keep it free we'll have to insert ads to streams and/or include ads on pages... Or just keep it free with no ads, but low quality... neither of those are the way I'd like this service to function.
* Added new features like autodj, better control panel, port 80 streaming.
RadioBOSS users, most likely, will have special offers for this server - eg. extended listener limits/lower prices.
