Since we were asked to leave feedback here for the new forums, here goes. I don't hate them, but they need improvement.
I already miss the sub forums that were grouped together like all of the creative topics being further broken down by building, sims, video, stories, etc. Too many things are jumbled together.
I don't like at all that the default for replies is by likes which I feel says the posting is a popularity contest and the more popular you are the more deserving of attention your posts (and you) are.
The post nesting is something to get used to. I like that I can reply to the original poster but I can also reply to another poster in the thread with out totally derailing a thread. I does make things harder to read.
I'm really hoping that after the initial we will in time be able to customize our avatars. I can understand the restrictions now as I remember very well what happened during the launch of the original Sims 4 board (I don't ever want to see that again!). Hopefully things will go more smoothly this time and restrictions will ease soon. It would be nice to have a ballpark on when that might be.-
