Replies are coming in. I wanted to take a moment here to say that I'm reading through them, and since I'll be out of town for a few weeks, I'll be making follow-ups when I return from that. (So don't stress out from a lack of reply! :3)
As for a bit more detail on the responsibilities... Ideally, I want to have someone capable of helping to advance the site in the long term. I don't mean with 'coding', but with forum topic cleanup in a similar way to what stuff I've done in the past. Even better if they can work with Chikara to establish a way of pushing through the large amount of new video clips we've gotten in the several years since an update. He's had a lot less free time lately, but I'm sure there's a way to help. So, yeah, adjusting forum topic tags is a big thing. Plus the basics like screening new members for bots/trolls, handling basic forum moderation... Overall, the 'moderator' side is super light. The tidiness aspect is probably more important. :3
