I got hassled by the accept rate police the other day, and, in improving my accept rate, discovered I can accept my own answers.
This prompted me to add my own answers to a few questions which didn't have a good answer already, which is a good thing, I reckon, as the next person to want an answer will find one.
However, I still had 1 question with a number of wrong answers, and to which I had never found an answer. I decided to add my own answer explaining I had given up, and taken a completely different route to solve the underlying problem.
Is this acceptable? Is it a good idea?
