How fussy are you about capitalization of your screen name? Personally, I often screw up other posters screen names. Not intentionally, you understand, just typing, typo, vision, screwyj keyboard issues. I will often shorten a screen name 'cause I"m typing on a cordless kranky keyjboard etc, And, since the capitalization was never an issue for me, it’s difficult for me to remember it might be for others.
so, who gets irritated at others miscapitalizing your screen name?
This is really a dig at Gfactor, right? 
I’ll admit that I was recently reminded of this by Gfactor, but it’s occurred before. I, personally don’t give a shit to the extent that I don’t even notice if someone capitalizes /doesn’t capitalize my screen name. But I know others care. t’aint against Gfactor personally, otherwise, it’d be in the Pit.
Life’s too short to worry about whether people get your name right on a message board IMO.
I love to capitalize Random words actually. It’s a really bad habit. But only the First letter of the word, random caps in the middle can get annoying over time*, but I can appreciate it once in a while. I just find capitalized words visually appealing.
I love the upper case R vs. the tiny little r.
But I don’t care about others doing the same thing. But i usually refer to myself w/ a capital, unless I’m feeling diminutive that day. roosh vs. Roosh. Come on, that R really just sells the whole name. It towers over the tiny foolish o’s and S’s. Only the H can come close even.
*I just realized the irony though in saying that, as the second O in my name is capitalized.
But I only did that for the formal sn. I prefer Roosh actually on a day to day basis. The oO is just an inside joke sorta thing.
Meh, people usually misspell my screen name, and I take miscapitalization as an extension of that. So no, it doesn’t bother me at all.
It doesn’t bother me when people fuck mine up, but I’m pretty anal about getting others’ correct (though if you’ve got some weird long name in binary or some shit, then all bets are off).
The only think that weirds me out (slightly) is when I want to use a non-capital name at the start of a sentence. But it’s not like I lie awake at night worrying about it.
