Responding to Comments

Does anyone familiar with Blogger know how to respond to comments?  Other than posting my own comment after theirs? Thank you and even if I haven't responded please know I read, love and appreciate your comments and would like some more. :D

**Update. In 09/11 I switched to the Disqus commenting system which allows replies and such. I really like it...except that when people comment via their mobile interface it doesn't connect correctly. I am notified of the comments but they don't show up on the site for others to read unless I reimport my entire comment database. I hope Disqus fixes that soon.
