These servers are divine! Even if I'm not a fan of deathrun-servers (already a worn-out mod). And the other 2 servers are very good and they have little anolog.
For example, I only know 2 open servers Obscurity (our and German (If I am not mistaken)). At German server have little online, there seems to have been for a long time no one plays. Freeze Tag, in turn, is also a very fun mod. There were times when these servers were constantly crowded.
I'm more than sure, they do not have people, because very few people know about them. The game itself is already old, and people, if they come to play, then, most likely, they will be played at a classical mode.
I believe that they need advertising. I am ready to organize the Russian community (on our social networks) on behalf of our clan, for the population among Russian gamers. Maybe it will bring us more active people. Also, we need to continue the YouTube channel and keep the stream, who is not difficult (my computer just does not allow it).
Maybe we should open a tournament server? It will attract people's attention. And we'll stream it. Let's make a button of donation for the participants. This will go to the prize pool and some percent on paying for servers.
