How can I change 'I agree to Terms and Conditions' text

How can I change 'I agree to Terms and Conditions' text.
I have looked on the forum to find this and done searches but cannot find anythin related. Please fdorgive me if I have missed it.
On the check out screen there is a string with a check box to say 'I agree with the terms and conditions'
We need to be able to change this text with the prepend 'I am over 18 years old and ....'
I have found the part in the template code that deals with this but it is only the variable [I think it is $agree] but cannot locate the text itself.
I thought I would try here before I grep for it and possible screw something else up.
Many thanks in anticipation
Steve

you must be taling about the 0.x versisions.

That is changed under the informnation page in the admin.

Daniel,
Thank you for your reply but...
V0.79 by the way.
Under the information page I can change the text of MY terms and conditions, however the string I am looking for is the one that appears in the checkout screen.
It reads (from memory) "I agree to the Terms & Conditions" where 'Terms & Conditions' is a link to the very terms and conditions that can be changed on the admin page.
It is not the terms and conditions themselves that I want to change - we have done that. It is tghe text that appears to the left of the check box on the checkout screen.
The issue is that the shop we are creating will be selling knives to the butchery trade and we just want to make sure that anyone using the site TELLS us that they are over 18, hence the string we would like to display should read 'I am over 18 years old and agree to the Terms & Conditions' and then the click the checkbox.

For 0.7.9, the checkbox text is found in catalog\language\english\controller\checkout_confirm.php

Thank you Qphoria.
Cracking good job. RIght on the button. and as many other superlatives that I can think of and even thjose that I can't.
Job now done. Thank you again
Steve
