Someone on the TBC server wanted this, and, being nice as I am, I made this.
(this is for the chainsaw)
First, we will download the add-on
click on the circled link

Click agin

Now comes the hard part, depeding on your unzipper, you need to find these buttons (I used winace)
Click on the exact button

Now find your blockland folder


After finding it, click the "ok" button or "extract"
Click yes to the following prompt.(if any)

And there you go, in blockland, click on the add-ons, and click all the things you just installed, hope I helped! (-:
