but steel there are sooooooooooooooooooooooooooo many types of biotopes. One thread would just end up a jumbled confusing mess. If your suggesting that the OP (original poster) make a thread about a single type of biotope and make it good enough to be a candidate for a pin ok, but a single thread about biotopes in general will probably end up next to worthless and a dead thread in a couple days. IMHO
