I don't see how anything is gonna change from him having a title that's higher up in the staff hierarchy, if it doesn't come with an actual change within the staff's role and mindset. If it's activity you want to increase, why couldn't he do it in his current position? Now it just seems like you want Wexter rewarded for having been an active member of the community who has organized events for quite some time. I don't think you really thought the whole thing through regarding his promotion leading to increased activity (if that's what you tried to say, that is).
This place is community driven, but having staff (part of the community...) that focus on trying to get the community going when it's circling the drain could be something to introduce. Maybe introduce a whole new usergroup or w/e, that focus on bringing content to the site and forums. I know there's quite some people who like writing and engaging in discussions, who stay away from the forums as they are today. You could example create a weekly thread about a topic relating to anime or anything really, that looks good and inviting for the community to participate in; Something that doesn't end up filled with "op is a troll hurr durr". These "troll hunters" are ruining more things than actual trolls. In these threads you could be stricter against nonsense, or create a board similar to the old debate board), so actual discussion is promoted and not just one liners, images, and name calling the OP.
Maybe a new thread should be created if this is something worth discussing, as this thread is gonna end up with the majority just bashing the OP for having created yet another "dumb thread".
