I'm sure everyone's noticed the real time Mini-chat down at the bottom of the forum main index page, right? I've noticed that who's in there and when is very "hit and miss" - understandably as 800 girls and all their fans obviously all have different schedules of when they're available.
How about coming up with some kind of once or twice a week scheduled chat - times when Charms and their fans know they'll have a reasonable chance of syncing up?
