First click on a blog post.
Then click where it says # of comments (ex 0 comments, 1 comment, etc.)
Click the Leave a Comment button (or sometimes there will just be a text box already there).
Type your comment.
When prompted to choose a profile name, select Name/URL.
Type your first name (or whatever thing you want to use: BieberLady, TacosRule81982, whatever).
Don't worry about the URL portion (unless you have your own website you want us to check out).
Click to comment.
If you have one of the other accounts (Google, MSN, etc) feel free to login with that. Otherwise just follow the steps above and have fun!!!
And remember to COMMENT, comment, comment on every post!!!
