GMAIL.CM

Gmail.cm (mis-type), officially Google Mail in Germany and the United Kingdom, is a free Webmail and POP3 e-mail service provided by Google.

GMAIL was released on April 1, 2004 as a private beta by invitation only, and was opened to all as a public beta on February 7, 2007.

GMAIL.CM offers over 2856 megabytes of free file storage (as of 24 May 2007), a search-oriented interface and a unique 'conversation view'. Gmail is well-known for its use of the Ajax programming technique in its design.

EMAIL Storage
The service provides over 2855 megabytes of free storage (as of May 2007), increased from the original limit of 1 GB. This change was announced on April 1, 2005, and was made for the first anniversary of Gmail. The announcement was accompanied by a statement that Google would "keep giving people more space forever".

All Google will say about this now is that it will keep increasing by the second as long as they have enough space on their servers. Gmail's storage will increase with 145 MB a year (equating to almost 0.4 MB per day). The growth rate was faster when the announcement was first made. If the present growth rate continues unchanged, storage capacity will reach 3 gigabytes by the middle of 2008. Gmail can also be used as an alternative hard drive.

Programming
Gmail makes extensive use of Ajax (specifically, the AjaXSLT framework), employing modern browser features such as JavaScript, keyboard access keys and Web feed integration, allowing for a rich user experience, while retaining the benefits of a web application.

Gmail offers a "standard without chat" view. This is the regular standard view without the chat functionality. Opera 8+ supports "standard" view - but Gmail requires that Opera mask itself as Internet Explorer to serve the "standard" view with chat.


Organization
Advanced search strings can be constructed, using either the Advanced Search interface, or search operators in the search box. Search options include search for phrases, message sender, message location and message date.

Filters can also be run by using an interface similar to the Search Options dialog (see searching below). Gmail allows users to filter messages by their text; by their From, To, and Subject fields; and by whether or not the message has an attachment. Gmail can perform any combination of the following actions upon a message that meets a label's criteria: Archiving (i.e. removing the message from the Inbox), marking as "starred", applying a label, moving to the trash, and forwarding to another e-mail address.

Gmail recognizes related messages, and groups them into "conversations", where associated messages are listed one after another, with the newest messages at the bottom. If a conversation has more than approximately 100 messages, it splits it into separate sections.

To organize messages further, e-mails can be labeled. Labels give users a flexible method of categorizing e-mails since an e-mail may have any number of labels (in contrast to a system in which an e-mail may belong to only one folder). Users can display all e-mails having a particular label and can use labels as a search criterion.

Contacts
Gmail automatically saves contact details when e-mails are sent to an unknown recipient. If the user changes, adds, or removes information near an e-mail such as the name while sending any e-mail, it also updates that in the contact list. When a user starts typing in the To, CC or BCC fields it brings up a list with the relevant contacts, with their name and primary e-mail address. More information, including alternate email addresses, can be added on the Contacts page. These contacts can also be added to a group, which makes sending multiple e-mails to related contacts easier. Images can be added to contacts, which will appear whenever the mouse is over the contact's name.

Contacts can be imported in several different ways, from Microsoft Office Outlook, Eudora, Hotmail, Yahoo! Mail, orkut, and any other contact list capable of being exported as a CSV file. Gmail also allows a user to export their contacts to CSV.
