Why “Necromant2005”?
To make a long story short, I was a big fan of Diablo II, and my favorite character was the Necromancer. It was cheaty character who could raise skeletons, summon golems, and build an army of undead.
Later, in 2005, when I was trying to create Gmail account everything related to Necromancer was already taken. So after a list of unsucessful attemts my nickname become: necromant2005.
That is the whole story.
