The primary function of CAST is to review websites.
Individuals submit sites for review.
The director also reviews the site and when approved writes a short description of what the site contains. Each site is reviewed for safe content, chatrooms, penpals, etc. For example, does the site contain bombmaking instructions, pornography, inappropriate language, etc. Once the site is approved, it receives a Seal of Approval as a CyberAngels Safe Site. The reviewers use the programs for a minimum of two weeks.
