With an initial storage capacity offer of 1 GB per user, Gmail significantly increased the webmail standard for free storage from the 2 to 4 MB its competitors such as Hotmail offered at that time.[11] Individual Gmail messages, including attachments, may be up to 25 MB,[12] which is larger than many other mail services support. Gmail has a search-oriented interface and a "conversation view" similar to an Internet forum. Gmail is noted by web developers for its pioneering use of Ajax.[13] Gmail runs on Google GFE/2.0 on Linux.[14][15][16] As of June 2012, it is the most widely used web-based email provider with over 425 million active users worldwide.[2][17]

2.Look at top right corner. Notice the red button with the label "CREATE AN ACCOUNT". Click the button.
3. Fill-in the form
3.1) Fill-in your first name and last name.
3.2) Choose your username. This can be quite tricky as usernames must be unique and you cannot choose a username that have been registered by others. Take your time to choose a name that you like. Combine the username with numbers (make sure the number combination is easy for you to memorize!) to make it unique.
3.3) Type your preferred password for two times. Make sure it is hard to be guessed and simple for you to remember.
3.3) Set your birthday. The birthday date is important for future references, e.g., retrieving forgotten password or username.
3.4) Pick your Gender.
3.5) Enter mobile phone number. Your mobile number is required to help Google identify that you are a person.
3.6) Enter your current email-address. In the case where you forget your password, Google may use this email address to send you the password.
3.7) Enter the CAPTCHA text. If the text is hardly readable, click reload button to get a replacement. Enter the text carefully.
