Most computer programs have an EULA (End User License Agreement) that you must agee to before you can use the software. I suspect many users scroll through but often don't completely read them. I'm
guilty of the quick click myself. There's nearly always language regarding the program's usage and users must agree not to alter the software. Most of this is common sense stuff and protects the authoring company from being held responsible for situations that might arise when using the program.

Legally, you may or may not be bound by everything you agree to, but who wants to have to find out. The state or country where you reside may have laws that determine what goes and what doesn't. The average person has no nefarious scheme in mind and just wants to use the program, but new rules may apply after you sign the agreement.

Some retail purchased software doesn't allow reading the EULA until you open a sealed package, at which point it's pretty much yours. Fortunately, many company websites offer up these agreements or may provide them upon request. This may be inconvenient, but a bit of homework may be beneficial if you have reservations or questions regarding usage. You may be able to access the program's company website from a computer where you're shopping, depending where you are.

It seems these agreements are getting longer and it may be increasingly in our best interest to pay attention to the details we used to ignore. Some companies are inserting provisions to alter the agreements at a later date, meaning we might agree to accept conditions that don't currently exist. We may be agreeing to advertising related issues or in some cases seemingly unrelated sections of our computers being accessed. I mean, who knows? If we've agreed to abide by whatever they decide down the road, well.......................

Not wanting to sound totally paranoid, I should state I believe most software supplying companies are straight up and freeware and open source programs can be absolutely terrific. I'm just saying I might start paying more attention to these EULAs, especially if they're ten screens long!
