I had noticed for sometime that various users had phrases appearing beneath their usernames, "pilot fish", "lagoon predator", etc.
It was only a few months back that someone made mention that these were "rankings".
Ok, that being the case, I understand that a "pilot fish" is a "minnow" in the gret ocean so to speak, and the "great white shark" is not the Australian golfer (Greg Norman) but our Shark.
I do not see a subject thread which addresses these and would be interested in how hierarchy of these terms and how one moves through them, I note that at this time I appear to rate as "lagon predator" which must mean something of some standing but of not the importance of one termed "Master of Corals".
