| Dec 16, 2014 at 12:53 | comment | added | amoeba | I would like to call your attention to the fact that katya's answer is currently marked as accepted by you, but is dangerously misleading and advocates something that should not be done. This is explained in Dima's answer (which also has more upvotes). Do you maybe want to reconsider and mark that one as accepted? Just so you know, one can always change which answer is marked as accepted. | |
