This is my left menu thingy in my profile here on meta:
This is the same on my own forum, where I’m admin (1.5beta1):
Notifications and the whole “Messages” section is missing on meta?
(Also Bookmarks, but I think that’s because I don’t have any bookmarks here. Pretty sure I have notifications and messages though.)
I do have the bookmark glyph in the avatar menu which takes me to an empty page with the profile menu on the left, with nothing selected on it. Similar with “view older notifications” from the bottom of that menu, which actually takes me to a notifications page, with the menu on the left, but nothing selected on it.
