I've detected two bugs:
1. Time conversion seems to be wrong. The time is currently one hour ahead for CET. I guess it's because US already has DST but Europe will change next weekend.
Pretty sure this is based off the 'server' time (where the site is hosted). No control over that one. Just have to live with it by manually updating your offset in your profile, or just wait till it's back in sync.
2. The "new" notification (grey icon) disappears on the main page ("Home") if one opens a board and directly returns to "Home" without opening the thread with the "new" notification.
Not a bug, as it's intentionally done that way. That icon only shows up when something new has been posted since you've last visit in that section. Doesn't matter if there is an older 'NEW' post there.
