Making a login

[AWantedHero]

I was wondering if there was a way to code this out in HTML or PHP. I am making a clan website from HTML but I wanted to have a login box for VB3. But if you manage to get the code for VB3, if you can tell me how to convert it to VB4 if I decide to upgrade, that would be helpful!

- Login Box and redirects you to the forum directly once you successfully logged in.
- Logout.
- A remember me box.
- Once you log in, if you go back to the HTML page, it would say "Welcome (Your username)".
- Also a php code for pulling out combat arm's clan page information.

If you could make this code for free or for a payment/donation, I would greatly appreciate it!

Thank you,

(Oh and by the way, this is for vBulletin.)
(I did manage to find this code but it doesn't redirect you to the forum homepage.)
