1- Using online services everyday without any skipping. 2- Losing track of time after making a connection. 3- Going out less and less. 4- Spending less and less time on meals at home or at work, and eating in front of the monitor. 5- Denying spending too much time on the Net. 6- Others complaining of your spending too much time in front of the monitor. 7- Checking on your mailbox too many times a day. 8- Thinking you have the greatest website in the world and dying to give people your URL. 9- Logging onto the Net while already busy at work. 10- Sneaking online when spouse or family members are not at home, with a sense of relief.
