I used them at the first of the year until about April and they didn't charge then. I am disappointed too because I had thought about using them again. Oh well, there are always other sites!
I don't know what you used dietwatch for but I use fitday.com to journal my food and other stuff. They do not charge for any of this type of service. I do not know if they charge for advice or questions though. Just thought you might want to check this out in case you didn't know the site.
