Anyone and everyone can be a repair tech. Give them the opportunity!
We're a community of people who want to get better at fixing things. Stay focused on that goal.
There are lots of websites out there for people to act dumb on. This is not one of them.
Remember when you were working on that really hard thing that one time? Imagine the person you're helping out is you back then.
Repair is hard! Let's make it fun and rewarding.
You know the guy. Don't be that guy. (thanks, flickr)
