Are we able to get them broken into primary groups for EU America ns and Asian. So trades are not flooded with cross regions? Thank you for your time.

Your region shouldn't matter too much. You can swap it and trade with someone from a different region.

Is there a better plan in place so topics don't disappear in under 3 seconds?

I haven't posted in there yet, I'm guessing this is intentional until the release of the game (or close to it).
