Do you ever wish that when the comments come into your email's inbox that you could simply reply to it instead of having to go to their blog and leave a comment or comment on your own blog and wonder if they would come back to read it??? I do...and guess what...It can work that way. You can just automatically reply.
All people have to do is go into their profile and edit it to "show my email address"
once they do that people can directly respond back to the emails.
Now everybody go and do this!
(one thing to note....this will allow an email me link on your profile as well)
