I am astonished that anyone would think that having an alias FOR ANY REASON WHATSOEVER is acceptable on a forum. If you cannot make your point with the one handle, what point is there in two?

The ONLY reasons I have ever seen for it is to bolster ones opinion, self-justify, and stir up trouble. Posting and deleting, and having aliases is the hight of netiquette bad manners.

And the sign of VERY poor judgment.
