Removing session hash or session....?

[Carnage540]

I want to make my url from this:

forumdisplay.php?forumid=62

to something like this:

forumdisplay.php?s=&forumid=62

----

So it looks nicer, and is easyer to copy/paste, etc. so....

- What would i remove?
- Is there a hack to remove it?
- Would it be hard to remove without a hack? Like i rather use a template mod

.....thanks! to anyone that can help!......
