I don't get it - cursor

I want to change my cursor on this forum: http://www.monkeymania.forumotion.com/ but I don't know the code and how to successfully use it.

Maybe you should have read this tutorial then.

Use the search function next time.

I did, but I didn't get it.

I understood it. Read it through a few times and look try to look at it from the authors perspective.

Thanks, can you just help me out?
