Hi,

I had been using the Knot's software but I found that it was missing some key features so I looked for other options. Sandals, the travel package company, has a free software program that you can download, no strings attached! I've been using it for over a month now and I really like it, it has sections for all the financials, guest lists, RSVP tallies, seating arrangements, thank you cards, etc. So far I don't seem to be getting spam so I feel safe recommending it. Here's the link:

Happy Planning!
