Hi pawelsz
you've been gone a while. I had the same problem with the new forum layout. By going to Phex (cross platform) and clicking general you will see the latest posts in each of the general sections etc.
I know what you mean. It would be good to go to Phex (cross platform) and see all the posts. It is a matter of realizing which forums are used most .. like General>General discussion. I don't like it, but at the moment it works OK. When the forums get busier, which is what is expected, it will be harder to do this.
I wish I had a better answer, but I've explored ths already and can't see one.
