SPELL CHECK question

okay you know when you type in any text box it underlines incorrect spelling which I like..... but some things it doesn't catch how can i make it catch it for instance the i - I

Safari doesn't have a built in grammar checker, just a spell checker.

okay but how about when you are using iChat and you type in for instance im and a red bar comes under it it should be I'm but it doesn't give you that option or i isn't even underlined to be I

It's likely because "im" isn't any sort of word. Try typing Im and you get the same thing (even in the spell check built into this forum) i doesn't give you a red line because "technically" you haven't screwed put any sort of spelling, just the grammar.

so it cant fix the grammer?

No it does not fix grammar just as baggsss mentioned in the second post in this thread.

alrighty then

is there an option like windows office has for auto-correct? then he could make an "i" alone automatially change into an "I", or fix any other mistakes that may commonly be made.

thank you
