DaNotoriousMC,
I believe the slot limit is hardcoded, so no. And on the jar of wine thing, that's actually a once a day thing. Someone asked about it before, but we kind of decided that it made absolutely no sense to be able to buy them jars of wine more than once a day - the actual text is buy everyone that comes in here tonight a jar of wine. So if you do it more than once a day, what exactly are you doing? Telling the barkeep to buy multiple jars of wine for everyone? How big is the jar, anyway? I imagine people would be happy with one jar, and buying them multiple wouldn't really affect their opinion of you, because it's kind of overdoing it. Like if I walked into a bar and bought everyone a bottle of wine, people would probably like me. If I walked into the bar and bought everyone 10 bottles of wine, people would probably start to think I was nutty.
