So, on Biology Stack Exchange, I found this question: Why do snails come out of the grass when it rains?
I did some searching and I found a very similar question that had already been asked and answered: Why do snails come out after the rain?
I wanted to flag the first question as a duplicate, but I didn't have the reputation to do so. Furthermore, I have no idea what to do in this case, if there's something that's obvious but you can't do anything about it. I suppose I could just wait for someone else to flag it, but I'm not always sure if anyone else will notice. What do I do?
(I checked and I haven't been able to find a similar meta question about what to do if you don't have the correct privileges).
