The day has finally come, UCP is now upon us. It is very likely that some things got bugged or glitched so please report anything you guys notice around and I'll pass them down for our Wiki Manager and Fandom Staff to get fixed.
Update 1: As you people might've noticed the PE notifications which appeared in the red box to the right aren't showing anymore. This feature (Wikia Notifications) was not ported to UCP and there are no plans for it to get implemented. We have moved the proposal notifications to the front page, and we also left a link to them in the top navigation.
Update 2: If you're browsing on mobile but is using desktop mode the search bar in the top won't show up. So either change back to mobile mode or configure your browser to show the desktop version of the page and it will appear.
