New Forums are ONLINE!
This issue marks the first time that Nuts & Volts content will be directly linked
to our online presence! We have completely rearchitected the forums so they now
closely reflect the content of the magazine. Every regular column now has its own
dedicated forum with the column author as your host! In addition, there are also
forums to support project articles for reader projects and even an area where you
can learn about what it takes to become a writer for the magazine! This new
forum design invites you to interact with the author(s), read about corrections or
modifications to projects, post questions, or just find and interface with lots of
other folks who enjoy the same things you do. As an added bonus, we have
populated the forums with example articles by each author so you can read them
there if you don't have time to read them here. We hope you find the new forum
layout exciting and useful. Please come by, have a look around, and introduce
yourself! To explore the new forums, just point your browser to:
Hope to see you online soon! :)
