I think the strategists could act as mediators for the TCG/Video Game forums. They're already staff, why choose a whole other group of members to do something another already existing group could do?
As for the 'being on for a certain amount of time', I know a few people who are exceptional members and have joined only this year. But that's beside the subject.
Route 24 is redundant, I just want to say. It'll just cause problems really. If the mediators (if there are mediators) need a place to converse, they can just talk to the moderators in PMs. That's what they're there for really - to talk to the moderators. They don't need a whole other forum that's visible to other members. It really doesn't show others how to become a better member, because I don't envision a lot of discussion going on there. What's there to talk about if the mediators aren't staff?
The more I think about it, the less I really think the mediators are necessarily NEEDED. I mean, there's always the report button. As Kevin as repeatedly said, you don't need to be fluent in the TCG to lock a thread. It would help strengthen the relationship between the members and the moderators, so that's a plus. I don't know, I'm quite wishy-washy on this subject. It's sort of like the Clan Council, whose purpose was even admitted to be to get veteran members staff positions. Although it was a successful group apart from the drama it brought, I don't know how successful this group would be. I mean, their moderator powers would be GREATLY diminished as mediators (by diminished I mean non-existent), so it wouldn't get out of hand. My fear is that it evolves like the Clan Council did. It would have to be kept under controlled supervision, which would be done, because the mediator would be in contact with the moderators, informing them of what's going on in the respective forum their were 'assigned' to, if that's the correct term for this situation.
But yeah, it's all opinions, speculation, and suggestions at this point.
