text: These children's guidelines have been developed with the recognition that Internet technology evolves rapidly and that underlying business models are still not established. Accordingly, guidelines are subject to change. In the unlikely event of such changes they will be posted on this page. If the changes represent a material departure from our current practice with respect to the use of children's personal information, the changes will be posted on this page thirty (30) days prior to taking effect and will not affect children's personal information previously collected.
