Hi, Arthur. Glitches are par for the course and already being repaired.
The small format changes will take a couple of days to get used to. Once you start using the 5 extra tools we've added inside of each post (Ignore / Private Message / Follow Member / Follow Message / Social Sharing) we assure you you're never going to want them taken away.
Remember, we went from AGORACOM 1.0 > 2.0 > 3.0 ... so we've been through this a couple of times. I'm sure you'll agree that it was a good idea not to stick with 1.0.
Best,
George
