I have problem with the WP-OpenID plugin. First of all it has a problem same as here.
With the WordPress thread comment plugin it's not working how it is supposed to work. As example, if somebody tried to use WP-OpenID and answers to comment always it can't make thread but placing the comment on first place makes new thread.
I'm really sorry for my language but I hope you understand me.
WP-OpenID 2.2.1 WP 2.6
