Out of curiosity I followed the first of Pierre's BioStars links from the comments on the FASTA lengths question, and noticed that our currently accepted answer bears a strong resemblance to this answer on BioStars.
I'm not trying to start anything, or accuse anyone here, but presumably we're not here to mirror answers already available elsewhere. So I'm just wondering whether there is a policy on this sort of thing, and whether anyone knows what the license for BioStars answers is?
