Final Death of Necroposting

You're requesting an exception.
Exceptions to the rules require justifications, not the rules themselves which have already justified their existence in some way.
You've yet to provide a reason why this is exception is necessary in any way with the options currently available.

I already gave my justification, the forum is not prone to problems that arise from necroposting. How is that not a valid argument?

If you were to view this as multiple copies of the same rule on each individual forum, it wouldn't just be an exception, it would be a request to remove one of those copies.

I'm still wondering why it seems so important to everyone to keep that rule on that forum.

From what I understand about posting a new thread, it shouldn't take more than a few seconds to put it up on a single forum. I understand that it takes time to write it, so why don't you just place it in the Open Canvas and give yourself a break? I don't see the reasoning behind OBJECTING from placing it in a section where you can update as you please, that is all. People are being so argumentative of the rule as if it has to be a big deal, and it just doesn't have to be a big deal. If you would give me a valid argument as to why, maybe I would accept why the status quo must change. It's not because I'm a psychophant authortitarian worshiper, it's not because you are arguing over a section that only has SIX threads where 1/3 of the threads won't ever be updated, 1/3 has been inactive, & 1/3 is solely composed of your own contributions, it's because there is no pineappleing practical reason why you can't just post in the Open Canvas and preserve your project until the day your plantain shrivels up in your grave.

So the moral is to just... do everything you're told and don't question it?
