How do comments work?
By reading some questions, I came to know that I should have get at least 50 reputation. But we have some minor doubts in the answers given by potential users. For that we don't want to post a question(duplicate to same) again due to inability to give comment. We are newbies and we don't have much reputation to do that.
I faced this issue so many times but nothing to do. Should we post unnecessary questions to get the reputations so that we can give comment or questions to a specific thread?
Is there any way to decrease the reputation count to ask a comment?
Example: @Mike, Hi mike, There is a question Adding users to sudoers through shell script and it was replied by WChargin. It didn't worked for me so I thought to give comment on that with the error description I have got. (But I am not able to give comment)
If I ask the same question again, I may not be able to get the attention from the same potential replier(Wchargin). If I give comment to the same answer, I am sure he will give suggestion to that.
