Leaving computer on all time puts excess wear on mechanical components (the hard drive spindle motor and cooling fans). Best compromise. First user in morning turns it on; last user turns it off. We leave our desktops on all time allowing for scheduled utility tasks to run during overnight hours. We also restart systems (to flush RAM and reset operating system) on a regular basis and routinely remove case covers to clean out any dust that may have accumulated, especially around fans and screens.

#3 -- Stop Popups! Never click inside window of a popup. Instead, close it by clicking on X in upper right corner. Many people are fooled into installing spyware applications by popups that promise to clean their system. If you receive a message saying it can help, assume it’s spyware and don’t click!

What can Wikis be used for? Wikis have spawned some interesting uses, including development of knowledge bases on both intranets and Internet. Product documentation, tutorials and online FAQs are increasingly created using Wiki collaboration. Other collaborative Wiki projects that have been spawned include a Wiki dictionary and directory of famous quotes.

Wikitionary - Wikitionary, a collaborative project to produce a free multilingual dictionary in every language, with definitions, etymologies, pronunciations and quotations. - http://en.wiktionary.org

Wiki Quote - Wikiquote, a free online compendium of quotations in every language, including sources (where known), and translations of non-English quotes. - http://en.wikiquote.org

Ultimately, Wikis are ideally suited for internal corporate projects or committee groups, when all individuals participating have same goals in mind. Potential exists for significant abuse when Wikis remain open in competitive areas.

Overall, Wikis are influential, shaping collaborative online content development, and are likely to become increasingly popular. Sadly, as a Wiki's popularity grows, it is likely Wiki abuse will grow.
