This goes in the direction of How to handle answers as comments, but is not the same:
I often see questions like this where the user who posted the question later finds the answer himself, but either modifies the question to say "update: I solved it" or adds a comment "I solved it".
I find this a little frustrating, as:
- I spend time reading and understanding the question to find out in the comments that this has been answered.
- If I don't know the answer and have a similar issue, I can not benefit from this question.
I could of course still answer the question (if I know it), but obviously the original poster has no more interest in an answer as it is solved for him.
How to handle this?
- Leave a comment that the OP should post his solution and mark it as solved?
- Flag for a moderator?
- Or even mark the subject line with '[already solved]' (I am not serious about this)
