Single post in Removing Post Upvotes

I could possibly support this for suggestions/announcement threads but I wouldn't want this to be implemented throughout the whole forums. Personally I use the upvotes in my trade shop/sometimes in temp trade threads to signify that I've already sent a trade and I know others that do this too. I can be forgetful sometimes, so it's a great way for me not to get confused without spamming my thread with a "sent" post after each post.
