A way to not show "Moderate by..."

You should be able to hide it via the stylesheets. A quick look at the markup shows that hiding "tclcon p" should do the trick. E.g:

tclcon p {
  display: none;
}

Open up index.php, and find (line 132):

                                <?php echo $forum_field."\n".$moderators ?>

Replace with:

                                <?php echo $forum_field ?>

No more "moderated by.." text

The Rickard way are better because u can't need to modif forum code just added it on your  style/imports/<yourstyle>_cs.css

tclcon p {
  display: none;
}

Adding it to the end of base.css should suffice.
