Since all of my links are created by an SQL(T) server, the links from within my site going to another part of my site should not be. However, if you come with a page not found error, there would eventually be a means to report it if it isn't done already. When a web site I don't have control over links to a page within my site, the error might be more common. In which case, once I learn of it, I would than make remedies to fix it. For example, this page is prob.xhtml. If someone links to this site, but links it as problems.html, than that would cause an error. When this arises, I would advise the site owner of the issue, and take steps to set up on my end in case the site owner doesn't fix it. One common solution would be to use a redirect command that the server would do.
If you notice a spelling error on the page, than I would want to fix it as soon as possible. I am not the best speller, and while I try to do spell checking on everything, I could still make a mistake. If this is brought to my attention, I would definitely strive to fix it. This would almost always mean to edit the MySQL database. Each and every weekday, I would work on making new changes as needed. Once, I have a bulk of changes, I would than update the database which could take the site offline for a minute since I usually purge the database to remove any flaws. The revision date only changes when something is actually modified in the content itself.
In the very unlikely event that there is a copyright, or display issue. I would also offer a contact form in which the person can contact me to voice their opinion on the issue at hand. All of my work is mine, and anytime I need to reference to something that is not mine, I would like to think I give due credit where due. If you feel this is not the case, however - I again still offer a means to notify me. If I find I am at fault, I would do what is needed to remedy the situation.
