Also, I read somewhere that when using a vacuum cleaner, you need to be very careful about creating static electricity, which can destroy electronic components. I never used a vacuum in my Desktop PCs, but I have been very cavalier in using canned air sprays to blow dust bunnies out of my PC. Probably froze some parts and caused lots of condensation in doing so, but I never caused any damge yet, and it always made me feel good to clean it out. My laptop does not seem to accumulate must dust or lint on its air intakes that I needed to clean.
I removed the IP address gadget because I felt it lets them keep statistics on every view by everybody that sees our post on Terry's site. Not sure if Terry likes or dislikes that. We can't see that data, but the gadget script creator webmasters can see all of it.
