Where to change the {$lastpost_profilelink} style?

[SvenUilhoorn]

It's in the template "forumbit_depth2_forum_lastpost" in the forum bit templates. Searched for what feels like hours but can't find it.. Assigning a custom class doesn't work neither, like 

<span class="custom-last-post"> {$lastpost_profilelink}</span>

..or

<a class="different">{$lastpost_profilelink}</a>

with .custom-last-post a{color: green;} and .different {color: green;}

Then adding the style I want in global.css (no underline + other hover state than default links).
