Felt Teeth
Greed is for amateurs.
I have two ideas.
The idea I like most that will be least productive: Send out a newsletter explaining that by a certain date, those under a given number of posts will be removed from the guild.
The idea that will most likely encourage users to post: A contest! Write down the names of guild members and the number of posts they currently have. At the end of the time period, subtract that from the hopefully increased number of posts. The person who has posted most wins a substantial amount of gold. I'll donate 20k to this.
Disorder, chaos, anarchy: now that's FUN!
I like both ideas Felt, in fact I'm going to add to it slightly.
Perhaps we start with the latter one, the contest and then say once its over and such that those who don't post after a certain date will be removed. So that way we have a little bit of productivity and a little bit of pure boredomness. (:
Mayhap that'll get them to start posting.
