I am going to have to disagree, if people want to have weekly events then by all means have events, you dont need to include a whole community in it though unless the whole community wants to come out of free will.
i often go into bh worlds with no people in the creator - i normally pk in mid but.
and i dont mean every week you have to come to bh, i mean everyone who wants to transfer money should wait till a certain time when everyone else is doing it.
We don't set this stuff officially but you can set it up yourself by posting in one of the RuneScape sections. Probably under the Bounty Hunter forum would be best.
