I am beginning to get very irritated by the minimum six character edit limit. It's my habit to try to fix misspellings and clear grammatical errors in questions, in order to improve site quality. Quite often I get the message telling me that I can't do that, because an edit has to be six characters. Then there is a helpful message saying "is there something else in the question that could be improved?". Well, no there isn't. That's why I'm making this one.
What is the rationale behind the 6 character limit? Can't the servers handle small edits? Are we trying to discourage people from correcting questions?
