Also, does anyone else have any suggestions for articles I could write on my blog?

So far I've done a few general tune up articles, an introduction to file sharing over the internet, and I'm going to be talking about printer sharing, multiple computers accessing the same mail account, and some general tips about roaming and cellular data charges.

Keep in mind that this is really just very simple things that will be more for explanation to average users, and the aim is to keep them out of trouble, while still giving them enough knowledge to crave more.
