I don't blame you for setting some boundaries around commenting. Having people denigrate either you or your readers and display open disrespect takes the fun out of this kind of forum - and there's no real excuse for it. Eventually, as bloggers, it's something we all have to think about. I had a hard time deleting offensive stuff at first, but after a few bad experiences, I don't have a problem with it now.

With regards to this particular post, though, I am going to expose the full extent of my complete un-savviness and ask two questions:

1. What is IRC and p2p?
2. I run Vista, which has a firewall, and I also apparently have a firewall on my wireless router. I have AVG that scans daily, and a Lavasoft spyware thing I do every once in a while. My brother, who is the tech guy in our family, says that's enough. What do you think? And how would I know if someone's using my computer for nefarious purposes?

Ok, that's more than two questions...Sorry.
