I, for one, certainly don't expect
perfection in online posts. I don't mind slang--this is basically the equivalent of informal speech. I don't mind the occasional typo, or mistake. I make more than enough of those myself.
And I certainly understand that when English is not someone's first language, they're going to have issues with it. It's far from the easiest language to learn.
All that said, I expect people to at least make an
effort at proper spelling and grammar--and let's be honest, you can usually tell, based on the sorts of mistakes, whether the proplem is a lack of understanding of the language or simple laziness. Ultimately, language is about communication. If you don't attempt to use the language properly (or at least intelligibly), what you're trying to communicate is likely to get lost, or at best be difficult to interpret.
Honestly, I'm of the opinion that if someone's post was unimportant enough to them that they couldn't be bothered to
try to communicate it properly, it certainly can't be important enough for anyone to bother reading it.
(Emergencies and other situations where typing is legitimately done in haste are, of course, exceptions. But I've not yet come across anything on an RPG messageboard that justifiably quallifies as an emergency.)
This, BTW, is also why I feel people who use "L33T speak" regularly and seriously (I have no problem with people doing it on occasion as a joke) should have their computers confiscated and be forced to repeat the 2nd-5th grades. But that's just me.
