Some ideas I have for the server to simply make it more convenient to the players:
An econo-bot, this is something I saw on gamebanana similar to scrapbot, only it sells common weapons, and if you get it going, can even sell hats, how it works is that someone calls it for a trade, specifies the item they want in the chat box (yes that means they have to be english friendly as they have to spell the name correctly) and it will tell you the price in metal required to purchase the item, which the user adds and the trade is completed. This would save chat from constant spamming of people wanting to buy common weapons, like pans, mantreads, or other weapons of the sort.
I am not telling you how to run your server here with this, but some of the users at night are causing problems and being trolls, and since all of the admins have gone to bed, there isn't much we can do about it, so a night time staff might be a nice addition for the convenience of non-american players, or players that just stay up quite late.
Also a VSH inspired tutorial? A server or pull up menu that explains tips/tricks and how to play on the different servers, as well as the rules for the different servers, just to hopefully lower the numbers of "useless" players because they don't know what to do.
I am not sure if this is a working model or not, but someone mentioned on the gamebanana forums a thing called troll-bot. It is a server ran bot that detects basic "trolling" and can be programmed to match the needs of different servers, and can automatically kick offenders, some of the basic functions the dude posted were language abuse, people walking out of spawn and hiding to go afk, and glitching. I can no longer find this thread nor a model of it on gamebanana, I will keep you posted should I find out more about it.
I think this is it for now, I will post on this if I get more ideas in the future~
