I have a unique request/

[Ukshep]

I would like to do something special and i have exhausted all other ways i can think of so i would love it if you could help taking into consideration im not sure if this is even possible.

What i need.

I would like to use if statements to add a piece of text next to a post in a thread if that poster is the author of the thread based off the ip.

Logically it would be something like. If the post ip is the same as the first post ip then do this.

Example but im not sure if its even possible Your my last hope.

<if $thread['ipaddress']  == $post['ipaddress'] then>Thread Author</if>

Anhy other suggestions to achieve this would be appreciated. Please note it has to be based on ip as i allow guest posting.
