What is the difference between a dot net site and a dot com site?
Dot net sites (e.g. bodog.net) are typically play-money sites so you can learn how to play online poker with virtual chips. Dot com sites (e.g. bodog.com) are real-money sites that require you to deposit real money in order to play. Some dot com sites also provide play-money tables – look at the name of the tables in the Lobby software to see if they are marked play-money.
