Your parent/guardian will be need to approve your KidzArt account. It will be similar to other features on KidzSearch, like this forum.
When a customer purchases your art, you would ship it to us. However, if it is just digital, you can upload it. There may be options for the customer to have your digital art printed and framed when they order it for an extra fee. There will be some processing fees that have not yet been finalized.
Trading art has not yet been developed. It is an option for the future. You must be an adult to purchase something using a credit card or Paypal. It is just like buying something on Amazon.
