I just "compressed" conditions for showing who's original author and avoiding it in the first post of the thread:

<vb:if condition="($thread['postusername'] == $post['username']) AND ($post[postcount] != '1')"><span class="originalposter">Original poster</span></vb:if>

This is just to avoid having two vb:ifs, previous work from DannyITR works just fine.

EDIT:

I also thought that it could be interesting to add another function, to link threads opened by this particular user, instead to link posts of this user as @thetechgenius made.

If you want to point to threads of a user use this code:

<vb:if condition="($thread['postusername'] == $post['username']) AND ($post[postcount] != '1')"><a href="search.php?{vb:raw session.sessionurl}do=finduser&amp;userid={vb:raw post.userid}&amp;starteronly=1&amp;contenttype=vBForum_Thread" title="Other threads by this user" target="_blank"><span class="originalposter">Original poster</span></a></vb:if>

And if you want to control link, i.e. how it looks when mouse hovers on it, use this in additional.css:

.originalposter:hover{
 color: gold;
}

Of course, you can choose your desired CSS controls.

Now you can choose if you want just plain original poster sign, or if it also leads to user's posts (credits go to thetechgenius), or it leads to threads created by user.

And of course, all credits for this great idea go to BirdOPrey5. Thank you man. :up:

EDIT2:

And just in case you want to use user name in title of link, use this code there in appropriate place:

{vb:raw post.username}

For example:

<vb:if condition="($thread['postusername'] == $post['username']) AND ($post[postcount] != '1')"><a href="search.php?{vb:raw session.sessionurl}do=finduser&amp;userid={vb:raw post.userid}&amp;starteronly=1&amp;contenttype=vBForum_Thread" title="Other threads by user {vb:raw post.username}" target="_blank"><span class="originalposter">Original poster</span></a></vb:if>
