Just starting out with tumblr. Still don't know if others can ask or reply to my messages. Have to learn and get info. From other users... 73's

If you edit your tumblr theme, you should be able to add links and other information.  Check out disqus.com. You can set up an account there, follow their simple instructions and plug in the info in your Theme. That way your comments section will work.

Also, add some info about yourself to your account/theme. That people know a little about the blogger and can better judge the content.
