I created a new profile field, then created a plugin with the below code on the postbit_display_complete hook
Code:
if ($post['field10'])
{
$template_hook['postbit_userinfo_right_after_posts'] .= '<dt>Fav Artists</dt><br /><dd>' .$post[field10]. '</dd>';
}
Photo of results is attached. They are in a multi line text box one under another but they always display in a row
