I have been surfing the internet for almost 15 years, and can help with anything from searching, staying safe, secure shopping, eBay, personal websites, downloading, keeping your kids safe and more. If I don't have an answer to your question, I'll say so honestly. Please note, though, that Google is your friend...if I think your question could be answered by a little research then that's what I'll ask you to do. :-)
I've been designing eBooks related to new internet users, and have bought and sold on the internet for years, as well as having built and maintained several websites and online stores.
Personal experience, and I am currently doing a home study course in IT.
