How do you use craigslist?

[Laura McQ.]

I've never used it before ... Can somebody explain how it works for me?

It's quite easy. Go to there site and give your email address. Then you will get an email you have to respond to in order to verify.

That is if you want to list something for sale. If you just want to browse and shop all you have to do is reply to whatever it is you wish to buy. Then you will be given a choice of how you want to communicate with the seller, i.e. Google mail, Yahoo mail, or whatever is your default mail program. I would suggest you buy locally so you can actually go to the sellers address and look at what you are going to buy.
