Support. Even if the mods can move the threads, often times they
just ignore it, unless users bring it to their attention. And a
simple line of code to just remove the start new thread button for
those two subforums (using their ideas) takes a few minutes to code
for a novice like me, which means it should take about half a
minute for Riako to add in if he really wanted to. It would stop
the wrong forums getting used for this one forum (and the bugs
forum too, maybe) and cuts down on the spam and the need for mods
to move threads from the wrong subforums.
