Which websites have details on online options trading?

One useful site that has lots of information on trading options is the NASDAQ site. You may recognize the name as a famous stock exchange, so any information here will certainly be of use. For individuals newer to the scene, Investopedia may be a better option. The site has lots of neat features, such as a dictionary for terms you don't understand, a page on trading strategies, and covers lots of the basics overall. A great alternative for the less savvy trader.
