I noticed today that I got +2 reputation for making an edit suggestion that was approved on SuperUser.
This surprised me a bit, as I didn't recall seeing it anywhere, so I consulted the FAQ, which lists the different ways of gaining/losing reputation in the What is reputation? section, only to not find anything that could explain a +2 gain there.
It wasn't until I found "Edit a question (from other user) and get +2 rep?" here on Meta, that I realized what was going on.
In short, the +2 reputation gain from an accepted edit suggestion is missing from the FAQ.
