There are a lot of methods to access blocked sites:

-With websites like Anonymizer who fetch the blocked site/ page from their servers and display it to you.
-Type the IP number instead of the URL
-Use a URL redirection service like tinyurl.com or snipurl.com.
-Use Google Mobile Search
-Use Google language tools service as a proxy server.
-Use a Proxy Server
-And many more

To access your email accounts we suggest to use a web proxy.

For Gmail use one of the proxys listed on Dontblock.info ( We tested proxy 1 and it worked)

For Yahoo mail use Pagemod.com . ( After you login the Yahoo mail interface will not be the normal one)
