Generally, this is supposed to be a Kantai Collection server. I've made a modpack with a bunch of mods pertaining to that. I've already checked with all their authors, so it's okay.
Sadly, my server will not be on 24/7, as I'd rather be able to see everything at all times. That means, on week days, I shall usually turn it on from 3PM EST to 11PM EST. On weekends, it'll most likely be on all day. The only rules are to use common sense and to not take this server too seriously.
This is the modpack: http://www.technicpack.net/modpack/kantaicraft.592307
