I see the point (okay, actually not really I mean, if someone has found a frog in his backyard, he could just tell where he lives..?), but is the flag thing really necessary? You probably won't understand it if I tell you that in switzerland it's kind of right-wing to wave around the swiss flag and being patriotic, since in your countries it's absolutely okay if not sort of requested, but you might understand that I find it very disturbing/embarassing to be forced to have that stupid flag flattering below my name in each of my posts >.<
I feel this way too, however, it really does make it easier for identification of species and research of laws.
Watching FrogTV because it is better when someone else has to maintain the enclosure!
