At the communities request I have turned on the Arma server again, all character saves have persisted. Currently we have around 90,000 unique players that have at one point connected to our server. Their items and ATM balance will still be there. The server was left down for several months due to low population.
Also, the Arma 3 server has been renamed to "S3K Wasteland", this is again due to a community request. We own the domain so I see no harm.
I'm likely not going to be holding population boosting events anymore due to Arma 3 being an old game, and because I rarely play. If any of the other admins would like to schedule events feel free to do so.
