Hmm, this isn't at all a bad idea.
You do have a valid point, and there are request boards in all of the FH Addons & Mods child boards, except for other Mods/Creations. So, it would make sense that we'd have an extra there.
My only concern is that we don't want to bring in an extra board if it isn't going to be used very much. For example, I looked at the other Mods/Creations board, and I saw a total of three posts asking for a certain game mod (the rest were finished products ready for download). Generally, three posts do not an entire board make, even if there are a few more hiding in older threads.
However, in the name of tidiness, we also don't want requests to be mixed in with finished products, if we can help it.
This said, it may be worth looking into, but it may also be something we'll need to live with until it seems like this "catch-all" board is really needing some extra organization (say, if more people were to begin requesting in here for the odds-and-ends that don't fit in the other sections). I'll throw this to some of the older staff, as well, since I wasn't there to see the thought process behind the first request boards that'd been made. I'm fairly neutral-positive on this, but I'm sure they'll be able to shed some light on it and add the board if seen necessary (be it now or later).
As always, thanks for the input, Buffy. <3
