Exactly. If you wanted to post in "Chat", for example, then you would first have to go to "Chat". Topics themselves don't dictate where the thread will be posted--you do. And if the thread is in an inappropriate area, the Mighty Mods will move it for you.
Can you provide some enlightenment?
I'm a grey-haired oldtimer with a bazillion posts and a gazillion articles posted. I did not know that. I thought new threads only got posted within the topics selected.
