Anything you post on beta.bitcointalk.org outside of Beta discussion will be deleted in the final merge.
Good to know.
I just find the new forum look awful. The old one was unique.
The look doesn't matter that much, the functionality does. AFAIK there will be more themes/this one won't be default (?). I dislike the current one as well.
Is there a buglist being maintained somewhere? To check if I'm not reporting something that's already known.
I'm not sure whether there is one outside of Github.
