MIR:
Well as for me, this is the first 3 letters of my real name, and it is a russian word that means "the world", so it is kinda i got the whole world in my hand stuff!

but he main reason is that when i was at school i had a huge intrest in space stuff, so one frnd kept calling me MIR at high school and soon it became my official name lool

then when we started uni, i did not even tell anyone about that nick,but some ppl donno how started calling me like that , i was like DUH! how did u know
and with every new work i start, now almost everybody calls MIR from time to time,even though there is some formal atmosphere at work.. but hehe even the owner of the company calls me MIR ..

as for BEEE (B triple E)...
it was meant to be BEE, cuzz i was at a net cafe,i was subscribing to anitonline and wondering what nick i would use other than MIR, so that guy responsible of the net cafe asked me for some help , so he said in my local language, "kif bitdaleh mitil il zor2ta ma btihday" , zor2ta = BEE.. so i thought that this is nice and it is so common in google and not easily traced
but BEE was taken... so as i was reading on the internet something related to the famous IEEE, i though BEEE would be fun too.. loool ... B can stand for lot of stuff lool (6)

so that is the story mainly
