Klein Bottles only have one surface so they are the easiest thing to clean
Also, perhaps a small suggestion: it would be cool if mod featured actually gets feedback from community or gms or whatever. It would help propel mods that have a small flaw reach public server status etc..
Most of the released mods are for sparring and parkours.
So is that server going to feature mostly fighting mods like aikido, abd, lenshu, wushu, etc. (of course new ones) or also sparring and parkour mods. Because i haven`t seen a official sparring server yet and i don`t know if people would join such servers.
I guess they would want to be op to change the gamerules.
So giving the two guys which are playing a "beta op" which allows them to change the gamerules but doesn't allow them to do the hotseat and kick command.
I'm sure feedback in some thread (this one?) would be more than enough. I can't imagine you'd need to implement any new features for that.
