Part of me wants to throw a contest to find my new handle. It has been a long time now that I have been Seabass and the reasons don't apply so much these days. Then again I suppose a handle is like a blankey you just can't part with.
If you're known with one 'handle' you should stick with it for continuity/consistency...
In your case no-one's ever heard of you so 'hey you' would work....though I think it's already taken....
Yes, Seabass... I know....I can run, but I'll only die tired...
