cool. it gives me a lot of confidence to hear these stories :-) Where did you initially "advertised" (I don't mean paid) ?
After that, did post it on some forums, and on the IPTV subreddit, which did give it a boost.
But I have not been posting it anywhere for the last few months now, it seems that the steady flow of new users just keeps pretty constant no and the most active users are the ones who just find it through Google.
