Regarding the multiple email account issue... other than using two
browser sessions it would be nice if there was a feature similar to
that offered by the google talk application. If you are logged in to
the browser session with an account other than that running under
google talk and click the inbox option in google talk a page opens
asking if you want to switch accounts. Similar functionality when
attempting to access the backend of a blog for an account not
currently logged in would be a step in a more useful direction.
