Hi Greg,
I use to believe only real names should be used also, however, over the years I have come to believe otherwise. As mentioned "biogeek" is a good reference as is Jim {megadeath}, both excellent reef keepers and even Julian uses an alias when he posts.
Sometimes it does go to far, as seen by some of the names and avatars. I just dont bother with them myself.
On a side note, I have read most of your writings, back to when you asked Julian in Reef Notes, what you should do about all the growth from your soft corals.
I thank you for all your contribution to the hobby, but dis-agree, only partially, with your views on tangs. But thats my opinion however and I have given up on the internet argument over them. And no, your tangs are not older than me.
