Present! Tech Club is always looking for ideas and speakers for interesting technology and science topics. If you have an area of interest, presenting is a great way to learn about a topic; help is available to turn it into an interesting presentation. Technology and science are rapidly changing so if you see a previous topic (see archives below) that you'd like to expand on or provide updated information, that's great too!
Tell Your Friends! Print out the Tech Club handout (click here) and give a copy to new Anthem Ranch friends and neighbors!
TechBoard! The TechBoard currently consists of Dan Magenheimer, Carole Gibson, Peter Beckmann, and Alan Kuhn. Board members participate in planning decisions, actively drive 2 or more meetings each year (by recruiting and/or assisting speakers/moderators for meetings; or personally presenting/moderating), and help drive future directions for the Tech Club. If you're interested in doing these things, please contact a TechBoard member.
