They should change that rule to read "three-cell radius".??Not many people understand 7x7.
Or, for those...others... "Setting up a shop or chat within three cells of any NPC (including signs) or warp will result in your character being jailed for twelve hours."
I actually had to think about it the first time I read "7x7".??Then I came to the conclusion that that just means a three-cell radius.??My way seems much simpler - but, of course that's always the case with our own ideals.??=p
Anywho, Droid, you gotta be in there on your char for a total of twelve hours (or w/e your punishment was). I'm not sure if this is breaking the rules (someone inform me if it is, please, so I don't break it should I find myself incarcerated); but most people have said they just @at in the jail until the time is up.
