I understand that BW was sluggish, but it's a good lesson for everyone, staff and members.
I think that it's necessary for members to have input on what activities they want included, and also, (unlike MBF) there isn't a persistent spark that can last for 4 weeks, let alone 8.
Organisation-wise, I think a member body would be more consistent than one or two staff who have to organise other stuff, and/or may be inactive for periods of time. (me, for example >_>)
BW is supposed to have two activities, a Secret Page and an Orb Hunt scheduled, but I can make those normal competitions if necessary.
