If you have ever wanted to know how to do something, look it up in wikiHow. This wiki is very comprehensive. You can learn to build a fire, write a song, hook an iPod up to a car sterio… just about anything.
One my students reported on the article titled: Use English Punctuation Correctly. It covers all the basics. It is a nice resource.
If you know how to do something that other people may not… share your knowledge. That’s what wikis are all about.
