I can understand that once in a while spellcheck might confuse "you're" and "your", "his" and "he's", "there" and "they're" and retypes what someone wrote.
But some posts are just littered with these and other spelling mistakes with a generous sprinkling of "ur" for good measure.
Is it unreasonable to stop reading someone's post just because the spelling is awful? After all this is not a literary club so anyone can write how they wish.
