I agree with the solution of a /msg to the Author, because this would seem to get the job done, and also cost the least.

As for my opinion on the importance of spelling in grammar -- If you notice the error, then it's probably serious enough that you should /msg the author. Spelling and grammar rules are like computer protocols. The rules of both are there to help aid effective communication.

This is especially true for people that do not know the language as well as others -- if you notice the error, chances are others with less understanding might misinterpet the meaning of the sentence, or have trouble understanding your unique "gift" at spelling a certain word.

I know that I am not the best speller, nor am I am terribly proficient at grammar. But I try to make a point of correcting my words that I give to others so that they will better understand my views. (It also makes me sound smarter! :P :) ).

Well that's it for me,
