I have some interactive forms that I want to put on our web site.  Immediately to the right of our logo, is our company name on one line and a brief example of what we do on another line.  It is in there as a text field.  How do I keep people from erasing our name and putting in their own?  Is there a way to lock it or protect it to make it difficult or impossible for people to alter?
