I have run into a problem with this hack. You can install it and follow the steps, but it doesn't show up in the postbit_legacy, and you'll have to add it yourself. I added mine right under where '$vbphrase[posts]' is listed.
Code:
<div>
<b>$vbphrase[threadsstarted]:</b> $threadsstarted
</div>
I did NOT see anything in the instructions for it in the text file. Please remedy this, unless I have missed something vital.
