Not for free to send it and save to computer. Almost $7 for a year isn't bad though! But I'm not sure if i'll be using this all the time though throughout the year.
Elaine R
Thank you for this program! It's so much easier than another I have tried and I have more to learn about usage when I have more time. Just trying to get something fleshed out relatively soon for now.
