We just rolled out a quick change that makes the discussion threads we manually created properly be owned by the person who uploaded the mod. If you're a modder, you may have gotten a varying increase in post count as a result, but for consistency, everything related to the mod, be it the actual page, or the discussion thread, is now in your name.
(We got a heads-up that since discussion threads for pre-discussion mods were made by moderators, there was some confusion since it could easily be mistaken as the thread creator being the one who uploaded the mod.)
