I think adding just one board to the forum named like "Terragen 2 Animation" for example would be sufficicient.
So there would not be so much compartimentalization as you may fear.
Also, the starter asked 2 different questions, one if there's a central area = thread about animation news. The answer is, no.
Planetside spreads news via changelogs or announcements. Clear enough.
But, he drops the idea of making a separate board for animation topics, mainly because it's much easier to find animation specific topics. I really agree about this, because like many here I often have to search for some specific stuff too and it is not convenient always since the search-engine is not flawless. It's good though, for sure.
So Oshyan I do not really agree with your conclusion that it was suggested just for news.
I understand your reasoning about the threads and traffic, but I find it a bit of an example of the polder-model approach, so the dutch way:
Just wait until it really becomes messy and unclear enough (lots of animation-topics scattered everywhere on the forums) and then see if we can do something about it. Which is in fact too late then.
Richard states perfectly that the latest pc's are well capable of handling animations and thus he expects an increase in interest, threads and traffic.
So perhaps it's useful to already start a separate board out of precaution. Won't hurt, seems to me
I hope you don't mind me thinking along
Cheers,
