I tried to edit SLaks answer to this question. I just wanted to correct the name of a function (see my comment on the answer), but as I found out on meta I cannot make edits with less than six characters. Which I understand, because edits should be substantial.
The problem I had was that I didn't know why I couldn't make the edit - I didn't get any message saying I cannot make edits with less than six characters... so I checked meta.
I'm using safari. Is this a known problem? What should I do when I want to correct minor mistakes like this?
