The generator has spotty support for Internet explorer and some browsers on linux. You can subscribe and receive the automatic weekly emails with any browser, but it will be difficult to edit them and make changes if the meal planner interface isn't functional. Before you subscribe, please play around with the free version of the generator at www.eatthismuch.com to make sure it works well for you.
If you're getting an error and you don't know what's going on, please send an email to support@eatthismuch.com and let us know what you're seeing. Please also include what browser and operating system you're using. Thanks!
