You'll need to create a new recruitment thread for the new forums. We'll be monitoring the volume in the server forums over the next week or so and may introduce recruitment sub-forums if the volume of posts per day and readability warrant them, but we won't be migrating the old threads over.
Allison, another quick question - you mentioned that after a few weeks you may add in separate recruitment sub-forums for each server if needed, does this mean guilds will have to create another new recruitment thread if that goes in place, or will you migrate the existing threads (those created after the server forums came online) to that new area?
If we do create recruitment forums, it will likely be within the week, and we'll go ahead and move all the recruitment threads created between now and then to the recruitment forums. Feel free to put the effort in to create new, fancy, updated threads!
