But one megathread for whole forum wouldn't be good thing IMO. Coronovaris is hottest topic in the world right. There is just too many people discussing about it in whole forum. It would be just huge spam megathread and discussion would be impossible there. But on the other hand, there is way to many pointless topics about virus on forum right now.
Its probably a good idea, but its up the the local moderator to enforce that, and if I've learned anything about local sections there seems to be a much more "togetherness" within the sections, and its probably better if each local section decides this among their community rather than a moderator acting on their own behalf. Technically, as long as the threads are substantial, and don't break any other rules I'd agree with a few others who posted here that its good to have difference perspectives, and different types of conversations about the current pandemic.
