Blogger says their blogs don't expire. This mean that if you set up a Blogger blog, don't even make a single post or make one or more and never update it for years, it is supposed to be still there.
Gmail Policy is different. Here is the Gmail Policy, last updated on June 28, 2004:
Now that Blogger have introduced New Blogger, a Blogger account is tied to a Google account which is the same as the Gmail account. Now if you start a Blogger account with a Gmail address as the username, and you don't sign into your Gmail for 9 months or more, what will happen to the Blogger account with its blog or blogs? This is what I to test.
I have set up 3 blogs:
Test Blogger Permanency
Test Blogger Permancy 2
Blogger Yahoo Permanency.
The first two were set up with Blogger accounts using Gmail addresses. I will not log into both the Gmail addresses, and not update the first, but will occassionally update the second occasionally. The third blog was set up with a Blogger account using a Yahoo email address as the user name. The first was set up yesterday - 19 September 2007. The other 2 were set up today - 20 September 2007. I will not sign into any of the emails Inbox used. I will check to see what happen to the blogs on 19 September 2008.
