Concerning c-boxes, I don't use them often at sites, and I don't need one for me to join a game. Even so, I always have OOC c-boxes available at my forum games, but.. They never get used much. I'm not worried about it, but..
A question for staff that don't have a c-box: do you offer any disclaimer, an explanation as to why there is no c-box? For players, do you want to see such a thing, or is it not a deal-breaker?
For my next game, a work in progress (moving a game from one host to another), on the original host: c-boxes are never used. However, for this particular game's migration, myself and my co-mod @Bonemeal just don't have the right timezones. We have 'boxes at our other games, but we only really use them for quick, random messages. The majority of guests, if not all of them, show up in the box at 2am our time. During daylight hours, we have various real life business to contend with; we're not staff who can chat for hours in the box, but whenever we do spot a guest- they're there for one minute or less and then POOF.
What sort of disclaimer can we put up, likely in the FAQ area or something- that would explain our reasoning behind the 'missing c-box', etc?
