It seems like we're waiting for someone with TEH POWERS to do it...? Or ...?
If I or Markus do it, then our only option is to create a new subforum entirely and delete the old one, manually moving every single post ever posted in that subforum from one to the other. I'm not interested in moving thousands of threads.
We need Chris or another administrator to install a mod into the server that allows us to merge forums. I've already pinged him about this (when this topic first opened), but so far we don't have that capability. It's probably a pain to install these mods.
