I could understand occasionally misspelling a character's name, particularly because a name is something which people as a general thing don't think about spelling. It's not like a 'dictionary' word, where people have to look up how to spell it, and to be fair some characters out there are never given actual written names, except maybe in the show's credits, so only people who really care enough to wait through/rewind the credits of their show to get the correct spelling of said character's name can say they have the correct spelling of the character's name.
And I don't know about you but I generally don't wade through a show's credits to find something which I don't even know what looks like if I have a fairly good idea of how to spell it already. Sure There was a show Avatar :TLA character's name was Ty Lee, I had always spelled it Tai Lee until I was corrected. I changed over without batting an eye, because to me, as long as someone knows who/what you're talking about, what does it matter what what the thing was spelled. And a good player should be able to portray a character such that you could figure out who they where without having to know their name.
What get's me is when people post, and you need a decoder ring to figure out what they were saying. I knew this player once, openly admitted to having three or four different things going while he was posting. He drove me crazy, it wasn't that his posts were poorly formatted or even that his spelling was poor, it was the little things that could have easily been caught had he just given his post a second glance. Things like tree being three, or three being there or vise versa. Those were particularly bad, because no matter what he typed, it could have been a half dozen other things.
I mean is it so much to ask to run your posts through a spell checker before posting them? Here we even have a built in spell checker, how hard can it be to notice the little red lines? And if you don't know how to spell something, used Google or any other of the ten thousand internet sources to find out how to spell it. It's good for you and it makes sure people get what you're talking about.
There's nothing in this world which concerns me more than the thought that I might be misunderstood. It leads me to religiously double check my posts, and often I'll scrap entire posts if they're not to the point enough. I tend to ramble because of it, going into absurd amount of detail about things that probably don't need it just because I want people to really be able to see it.
The more I interact with the world, the less I want to...
