First, you need to set up a blogger email address to which you want
to post (it's going to look like this: your
googleid.securityhandle@blogger.com) and specify whether you want to
posts immediately published or review them.
And then you can already start mailing = blogging.
Only prob is that I don't use blogger that much - I only have a
blogger account to be able to easily comment on blogger blogs. I much
prefer Wordpress - but then I have a wordpress.COM account and the
posting via email service only works on wordpress.org.
What I could do, however, is post via email to blogger and then later
import the posts to wordpress.
Reason why I am exploring this is that some employers monitor their
employees' internet use and do not appreciate if they blog at work -
so I am looking for ways I can recommend how such people can work
around the monitoring.
