While logged in, click "My Profile" in the top navigation menu and click on "More Options" which makes an array of options available for you to toggle. The third option down from the top is for enabling/disabling comments on your blog posts. If you do not want other users to be able to comment on your blogs, toggle the slider off by clicking on it. You can enable comments again at any time by clicking the toggle again.
Well, hello there :)I'm not going to put a lot on here, because that would take the fun out of talking to each other. If you want to know anything about me, message me. But I will say I am established in life and don't have time to play games.
