I did not close it earlier because I was away from the internet for four days due to a trip. I'm not on 24/7...
I also explained why I closed them in the threads as well - the section is not for creating things for HGSS when we already know what's in them and there's a thread for creating stuff in new games/generations in another section already - no need for repeat threads, hence one thread did not fit in the HG/SS section at all. (And was reported as such).
As for the Hoenn one I did not feel there was any real need for discussion on something not in the game and as said there wasn't not much point for further discussion on it - little point and if it's allowed than one should have threads on what if sinnoh is in the game, the character gets a car in the game, etc - just not necessary. (And previous speculation on Hoenn being in HGSS ended up with a lot of spam - I'd rather close the thread than have it continue that way, especially as the thread already had off-topic posts). That's why I closed the threads.
