how do i remove the sticky: prefix?

[zeroality]

I looked in the showthread templates, as well as forumdisplay templates. I also downloaded showthread.php and forumdisplay.php and couldn't find it anywhere. I tried changing the phrase to &nbsp ; but that leaves a noticeable space and you can't leave it blank.

Make a new plugin with the hook (forumdisplay_start)

   $vbphrase['sticky_thread_prefix'] = '';

Still works, nice.
Any idea how i can make the thread bold then?

Make a new plugin with the hook (global_start) worked for me!

$vbphrase['sticky_thread_prefix'] = '';
