Well, if he is then Fiedlerhater was his first personality. Go back and hit the "search" function. It is next to the "message list" button.

Then type in "dolphin" (you must spell it correctly) in the "author" block, then change the time setting to "all dates."

run the search and come up with the first post by "dolphin".

Then follow the above but putting in "fiedlerhater".

You will see that Fiedlerhater has been here long before dolphin.
