We just added "Ask KidzSearch" as category and included your question in it. That is a great suggestion! Please use it for feature requests, reporting problems, etc.
We are actually in the process of completing an e-mail for kids and will have it out soon. However, you will need your parents permission to use it. As soon as it is ready we will make an official announcement about it. It will appear as a top-level menu choice. We will probably give early access to it for KidzTalk members.
