| • | Allow anonymous comments - trackback comments are in fact anonymous comments, so this option needs to be enabled for the comments to be inserted |
| • | Open comments for - this option defines how long after the insertion of the blog post will inserting of blog comments be possible; trackbacks can also be inserted only within this period |
The Allow comments option must also be enabled on the pined blog post's Form tab so that the comment can be inserted.
