Teach Parents Tech is obviously designed for children to help their parents, but it could be used to help your colleagues down the hall too. You can customize your message so that it isn't addressed to mom or dad and is instead addressed to a first name. Even if you don't use the email template provided by Teach Parents Tech, you may find the site to be helpful in finding tutorial videos to embed in your blog or website.
