I tend to pick forum NICs that soon start to aggravate me, it was different when i was gaming here i never picked a silly name, though the first one i used was pretty unimaginative as it was just the nickname i have always been known by IRL.
And i was going nuts some times removing my clan name, and just picking some random name and started the slaughter, and doing that i would soon get more offers to join other clans, but i have never clan shopped, i find this bad form.
Actually if you call me by my real name, there are a good chance i will not react, and its not that i am inconsiderate i just hear it so rare.
