If you're already familiar with ehow.com, then you probably don't need to read on. If you aren't, you should check it out. This is a great site that is driven by readers who write short articles on how to do almost everything. Really. Need to know how to shave your legs? Find out here. How to wire a lamp? How to make a memory quilt? How to put up a tent? This site provides directions for just about everything you can think of.
Another nice feature is the paid writers program. If you can write, be sure and sign up for this. You can publish articles till the cows come home and won't get paid a cent until you sign up for the paid program. They charge something like a buck a year if you don't write enough to get paid $10.00 or more. Ehow only pays through Paypal, so you will need a free Paypal account, but doesn't everyone have one of those anyway?
If you don't write much, you shouldn't be intimidated. Ehow's template pretty much sets everything out for you. Their articles are in steps (they prefer 4-6), with an introductory paragraph and a closing paragraph, if you need them. Adding pictures is great, and will generally get you some money faster, but it's not required. You can also add some video if you're so inclined.
You can check your account to see if people are reading your articles, and readers can rate your articles with stars.
And the best part, given enough time, you can learn how to do everything!
