...Except it was a duplicate thread, created well after the other had been posted, and there have been instances where other duplicate threads were deleted instead of locked, to keep the boards less cluttered.
Seriously, let it go man. You cannot own a thread topic. You can't take it personally when somebody beats you to posting a thread of the same topic, especially when it's as common as a "resolutions" thread.
Also, other mods have deleted their posts after an argument to clean up the thread. I can't name any specific instances of this happening, but I do remember it occurring in threads that were otherwise pleasant, but had been contaminated by flame posts, so the mod went through and cleaned up all posts - including their own. It might have been Jeku, maybe, the more I think about it.
I have seen so many users complain that the mods are personally against them somehow. They aren't against anyone, don't take this personally, it's probably just a big misunderstanding. Just accept it and move on! Don't begin the New Year with this attitude - have a beer and celebrate!
