Is adding notes for beers no longer possible?

I am wondering because I cannot find the link anymore and I figure it must have been intentional or I'm just missing it.

I wanted to put a little note on a beer in the database that some friends brewed, but I also just drank a session IPA listed as an American Pale Wheat Ale despite having no wheat in it at all.

What's the protocol now when details need to be fixed or you want people to have specific information about a particular beer?
