After nine years of running this XMPP server I am still happy about it! I receive a lot account creation requests, thanks, kudos, support questions - everything is great! The huge traffic and the growing number of active users is astonishing!
But sometimes new hardware is needed and the electricity bill has to be paid. I am fine with that but maybe you would like to support the future of the server by donating a small amount. Until now I offered Liberapay and Ko-fi but after being asked about this I have added cryptocurrencies, e.g. Monero (which is the most privacy friendly one), Bitcoin and Ethereum.
You can find my wallet addresses on the donate page - thank you very much!
