Today, most children already want to have an email account (or other messaging systems) before the providers allow them to (before they turn 13.) A method that allows them to start doing so at younger ages and also teaches them best practices might help.
The current system could be augmented with an option for younger kids, where every message first goes through their parent or guardian. At a younger age, the filtering by a parent would probably be less of a problem than when they are teenagers, especially if the service provider mandates it for younger ages. The parent could then see how the child is using the messaging system, block a message if it’s a problematic one, or let it be delivered if it’s ok. Then talk to the child to explain what was wrong with it, so they can learn how to use the system well and what to beware of.
You need to know your options now before guests arrive for dinner.
A text messaging based bot that can understand the context of wine and food pairing. You just write what you are going to have for dinner and optionally what wines you have at home, and you will get the wine recommendation for each course or the whole meal if you want to limit it to one wine. Optionally, if you have no wines at home, you can also get a list of shops around you that stock the recommended wines.
