Reminders to posters to mark things answered
If there are suggested answers to a post and the original poster hasn't selected an answer or marked it answered in, say 7 days, they might get an email reminder, or be prompted upon login to review their open questions list. Hard to know what needs answers with so many not marked as answered.
It is a good idea, but as we are just beginning to implement email notifications so it could be a little while before we get to this.
For now know that anybody logged into the site may mark a question as answered (or unanswered) so the hope is that those question-answering-types like yourself will mark them answered when you think they are answered (and anyone who disagrees may undo it). The hope is that this will be more effective than encouraging those who may not care to come back to do so themselves, but we shall see.
