I was reviewing the users' first answers,
and I see a lot of people
who has answered his own question, but hasn't accepted it, because of:
- He's new on the site and doesn't know that answers can (should!) be accepted.
- He's new on the site and thinks accepting a self-answer is a bad thing.
- He had to wait to accept his answer and forgot about that.
- He intentionally leave it unaccepted (very few cases).
And I have to make tons of comments asking those people to do so.
Wouldn't it be great to let the site ask you to accept your answer?
I know there's a waiting period: if it hasn't expired yet,
remember the user to accept his answer when it expires.
For example, by showing a notification or sending him an email when
the waiting period expires.
