If there are problems with setting up AnyMeal, have a look at the page of frequently asked questions. You'll find the contact-information there, in case your question isn't answered.
I appreciate feedback by developers and users. You can drop comments at the AnyMeal KDE-Apps page. The AnyMeal Freshmeat page allows you to submit a rating.
I'm interested business stories. The license allows you to use the software commercially. I'd be particularly interested in feedback from professionals (restaurants, hotels, supermarkets, web-services, ...).
If you file in a bug-report using the AnyMeal Bug-Tracker at Sourceforge, you can subscribe to get informed by e-mail, when the bug was fixed or the feature was implemented. Depending on the complexity of the task, this may take some time.
If you want to stay informed about new releases of AnyMeal, you can subscribe at freshmeat.net.
