When consulting our own profile, we have access to the list of the responses (I think, comments on our answer).
Sometimes, the following scenario happens: I have two or more messages in my inbox, both require some clarifications on my answers. So I click on the inbox, and this one then becomes as if there was no message. Clarifying the first answer may take more time than I expected, and I cannot address the request of the second message. Then there is the risk I do not come back to this request.
What I suggest is the following: in the responses list, mark the comment as "answered" if we made an edit to this question or post a comment (in the same spirit of replied e-mail in a mail box).
In that way, when the described scenario happen, we go the the responses list and address the unanswered requests.
What do you think?
