One setting that you might want to tweak soon is the one that sends you an email message when you get a comment.  Any time a new system is introduced, you need to check to make sure that your settings were migrated or if defaults were applied.  (Don't I sound technical?)

Anyway.... if you want to continue to get emails messages when a comment is posted to your blog....

login
(down by "new entry")  click on "settings"
up toward the top of the tan area, click on "comments"
Look for this line:  Comment Notification
Make sure this one, "Yes, email me each time a comment is posted." is marked.

Feel free to browse this page and change other settings too.
Click the "Save Changes" button at the bottom.
