I've been looking through the site and I'm very aware of some stats that we're lacking on for the beta to graduate.
There is a large proportion of good answers that have been up voted by the community but not accepted by the op.
Now this doesn't look quite like the typical 'hit and run' style of question - as the OP has gone on to ask other questions too.
So on this note, is it a bad/good idea to perhaps pop a gentle reminder in a comment recommending accepting the answer (if they found it suitable). I think some people either forget to come back and mark it as solved, or are waiting for more/better answers - but even then, I think a reasonable time limit should be applied.
