Here are a few sites I try and contribute to every once and a while:

  • Android Forums
    • I go here and provide helpful tips and tricks for the Galaxy S3 and Nexus 7.
  • GameFAQs
    • Any game I play, I try to contribute to that game’s board section.
    • I don’t go here as much anymore, but if I do, it’s for any kind of console support.
  • XDA Developers
    • Same as Android Forums, except on the rooted device kind of tips and tricks.
