Especially if the question and answer(s) are very much new, say less than 12 hours or even 24 hours, is it ok to ask OP to accept the answer, that is added by self or someone else.
Even if the OP is a new comer, it is not good to do so, considering low number of views and votes.
Don't we need better ways of telling the asker that it is better to accept the most suitable answer, by means of ribbon above the unaccepted answer, only visible to the asker?
