(Archive Today is a time capsule for web pages. It takes a 'snapshot' of a webpage that will always be online even if the original page disappears. It saves a text and a graphical copy of the page for better accuracy and provides a short and reliable link to an unalterable record of the web page.) Disclaimers:

Use at your own risk. No liability is accepted for any loss or damage.
