Apologies for doubleposting, but because this thread has died down a bit and I have some concerns as to whether or not anyone on the farms is still interested in pursuing making a dedicated community server, I'm going to link some resources that would help someone get started with hosting a server first and foremost.
This guide from reddit is an excellent baseline for getting started on hosting a server. For budgetary reasons, I would highly recommend considering hosting the server on a VPS, following the hardware requirement guidelines detailed within the guide. Whoever decides to do so, I'd suggest paying out of pocket for the cost for at least a month, maybe two months if the interest and player activity remains decent and constant. After that, if interest continues, it might be prudent to look into creating a PayPal or some other form of donation-based service for the community to pay into to help cover server costs. Upgrades and benefits from doing so can be decided upon at a later time when it becomes relevant. For now, just providing somewhere for the farmers to play on will be well and fine enough.
Also note that the KiwiFarms community server
does not need to be listed in the BYOND server listings in order for people to be able to play it. As long as someone posts the IP address for the server here, everyone can connect directly to it through BYOND. This way, you can keep the server's participation limited to farmers instead of having randoms pop in and potentially shit things up.
Now, because I recall seeing Beestation mentioned as server code people would like to see used on the server,
here is the github for Beestation's regular SS13 server. Follow the steps from the reddit guide linked earlier, but use this git as the source for whatever's necessary.
Hope this provides some help on where to start with getting the ball rolling on this idea.
