in my couple hundred pages of notes and designs for the basketball sim game im working on, there is a page dedicated for 4 a day worlds, in which users never have to log on more than once every 12 hours (except recruiting), and rarely more than once every 24 hours (2-3 times a season, i believe it was). its very possible, and im just not sure why WIS would not use a model like mine, but i would prefer not to spell it out for them, not that they would ever listen (if they listened, id never have retired in place, and never would have started a project to create a better product). my 2/day world design NEVER ever forces a user to sign in more than once per day, except in recruiting. although ironically, my 1/day world makes you sign in twice per day, all the time.... (just kidding on that last part)
