This question already has an answer here:
Like lots of stackoverflow members, I'm trying my best to answer community questions, because I really believe in that kind of help.
Every time I ask for help, I spend a lot of time to ask clear questions, providing code and examples. I reply to comments asking me for more details. I vote for useful tips and finally I mark the correct answer because it helps the community and I can say thank you to the user who helped me.
I'm really angry and disappointed by people asking questions, obtaining the good answer in less than 10 minutes and who never mark the answer as correct or never give a comment to explain what is wrong with this or that answer.
Is there a reasonable length in time where the question is considered as "over" and the answer with the most vote would be considered as okay?
Is there a kind of reminder or alert to ask the user who asked the question to validate the answers to the question?
These 2 questions, in my opinion, deserve a talk and eventually a new feature to be implemented on stackoverflow.
