Here's a couple...
  • Freenets
  • Securing your networked PC - and why it's important
  • How to set up an OSS desktop (maybe w/ a list of OSS application 'substitutes'?)
  • Fun with Scripting
  • Web Authoring basics and aesthetics
  • Home Networking (connection, file, and print sharing)
  • Game Review
  • PC Hardware recommendations and comparisons

Does this help?
