Changing your settings in Gmail ..

To change your preferences, just click the gear icon  at the top of any Gmail page. From there, select Mail settings and navigate to one of the appropriate tabs:

• On the General tab, you can change your language preferences, select display pictures for you and your contacts, or set up a vacation response. This tab is also where you'll find general display and navigation settings for your inbox.
• For 'Custom from:' options, setting up Mail Fetcher, upgrading your storage, or changing your Google Account Settings (including your Gmail password and security question), select the Accounts and Import tab.
• Managing labels and filters is easy with the Labels and Filters tabs.
• If you'd like to forward your mail to another account or use POP1 or IMAP to download your mail to a desktop or mobile client (Microsoft Outlook or an iPhone, e.g.), click Forwarding and POP/IMAP.
• You can also adjust web clips settings and learn more about them on the Web Clips tab.
