1) For no reason that I can see, today PW saw the word "link" as in need of punctuation. As in "l.ink." The odd thing is, that I used the word six times in the document and it only suggested it once.
2) It pointed out the missing preposition "to" in the phrase "love to meet you." The "to" was exactly where it was supposed to be. I've seen this a couple of times lately at the end of line breaks.
