OOC, any old level of grammar and spelling is fine with me. I definitely prefer to RP with more "literate" people though, and I must confess the tiny mistakes like "your"/"you're" do get to me a lot XD I try my best not to comment on it however, and honestly most of the time I just think to myself "They'll get better, they're probably doing their best to learn" or "It's a typo, ignore it".
It's funny, when I started playing FH I was squarely in the semi-literate bracket. I looked up to the literate players, but at times they did seem a tad...not snobbish, but perhaps just intimidating because of the amount of attention they put into their typing.
After I moved into a more literate style, I'm afraid to say I did become a teeny bit high-and-mighty for a while >.< I would love to say "I can understand it if you're using a phone and you only have one thumb to work with. On a keyboard you have all ten digits, so why doesn't anybody seem to use them?" (which I guess is still valid if English is the person's first language and they genuinely are just being lazy when they have the ability to spell things fully)
At this point I figure it would take far too long for me to correct every spelling/grammar mistake or typo someone says, and it won't really get me or them anywhere.
Someone mentioned the idea of a FH school(which is awesome, provided that there are enough pro-active users who want to join in), and it reminded me of a particular experience I had with an older group I lead. This group was mapped, and I happened to get three or four people joining at once, all of whom had never installed a map before. That was fine, I didn't mind teaching them, but they just wouldn't listen half the time and got confused even though I might have explained the same step three times. I dunno. That's less of a literacy thing, but they were evidently all new players. Not entirely sure what point I was trying to make with that, actually...probably something like "Most of the people on here are lovely, but it sucks when they're too hyperactive to pay attention to important things they asked about".
Uhh...I appear to have lost my train of thought to an extent...muffins for everypony, I suppose. *throws*
