(NS)FAQ: What's a "beeljo"?

Before addressing the topic referred to in the post's title, let me first explain that a (NS)FAQ is a (Not So) Frequently Asked Question- sometimes so not so frequently as to be equal to zero.  Then again, sometimes the best time to answer a question is before it is even asked.

So who, what, where, when , why, and/or how is a "beeljo"?
It's the first two letters of my last name followed by the first two letters of my middle name and then topped off with the first two letters of my first name.  Thus: "beeljo".
