I have used this for the last 4 years and could not live without it for filling in all the freebie sites. There is a free version available but after the second year I bought the pro as I had so many passcards and wanted to set up different identities, so I could quickly send mom and other people stuff. This is similar to Gator but DOES NOT HAVE THE SPYWARE that Gator has.
