ok 1st of all ,

i want to make a part on my site wher u can register and login , and also create ure own account, with passwords and usernames.

but ive asked this question before and ther reply was " why dont u use php
but i dont know wat php is

can anyone help me with both questions?

PHP stands for PHP: Hypertext Preprocessor. It is a server-side scripting language. It's like a coding language that your browser never gets to see, because the server executes the code before it sends it to your computer. So when you view the source of a site that uses PHP, you won't see the PHP code, but instead html. Does that help?

Now I don't know much about coding in PHP, so I can't help you with coding for what you need. The farthest I've gotten is a simple contact form.

Bravenet.com (http://bravenet.com) should have something like that under the "Free Tools" section.
