Yes. You can restore previous changes made on “pages”. By default, WordPress has two post types. You can also have custom post types called anything [i.e. tickets, or calendars etc.]. The two default post types are “posts” and “pages”. Pages have a screen option called revisions which allow you to browse through previously saved pages. You can restore any previously saved post if you have the role “editor” or above. This feature can be enabled on any post type by a developer, and is enabled by default on pages.
Here is a theory which is a tautology: “Science” constitutes knowledge which is known to be false. Popper . i.e. You know, via the mechanism of science that you cannot, for instance, eat rocks for food. It is false to say that rocks are a food source for you; Science. So that particular scientific theory [about eating rocks] can’t be true or false, because it doesn’t make a positive assertion. Therefore it is scientific to say “it is false that rocks are a food source for me”. This theory of knowledge, might be the only theory that is a tautology, hence “true”. Basically, it is a theory that says the only thing you can know for sure, is that you make mistakes in what you know – for sure. As far as math being true, or any other positive theory, see the I-Ching, all of human history, or perhaps the metaphysics of 90% of philosophers who have ever lived. “Math” and “science” are giant ponzi schemes of black swam fallacies, perpetrated by grab assing reputation whores. Scientist talking about the big bang: “Give me one free miracle, and I can explain it all!” McKenna
Freelancer.com is ridiculous for “design” contests! I’m not going to say the price, because it isn’t fair – given the quality of work. These guys are GOOD. Hazem actually submitted TWO entries that were good, and was able to adjust the design when requested. If you’re looking for a good designer, I’d definitely recommend Hazem.
