What's wrong with splitting? The whole idea of a forum is to have in-depth discussions, and this is a separate conversation from il's post about the antihack.
Advertising, helping new players, hosting tournies etc. are all great, but those are things everyone can do. Admins have a finite amount of time that they can devote to wc2, same as everyone else, so they tend to do the things that everyone else can't do, like improving the server itself and keeping it running. Paying bills. Administrative stuff. Would you prefer e.g. that iL sat in the channel all day telling new players how to host rather than developing an antihack? Or that I had hosted a bunch of tournaments rather than building and maintaining a modern website?
Another point, the people who actually do the things you suggest tend to get nominated to become admins anyway. Remember when Rit was here for like a month and took a bunch of initiative? Challonge, Google calendar, some other stuff. He was nominated more than once. I personally don't feel like people who do these things need to become "admins" though. Maybe server mods, or "community leaders" or something, based on what they contribute.
Bottom line: wc2 needs volunteers, not finger pointing. Everyone wants to pitch the ideas, no one wants to do the work. And that's understandable, we've all got shit to do.
