Grannyx....Sometimes on here I write "Their" instead of "They're" or "There", sometimes I split infinitives, and even end sentences with prepositions.
You'll go nuts nit-picking spelling and grammar on here!
You are, of course, correct about trying to keep up on FR and bad usage. I thought since we were on a home school thread, it sort of seemed appropriate. :)
