Sign up form receiving bogus registrations

Random code generator?

[Compworld]

I've been receiving a lot of bogus sign-ups from Asian countries. It is putting a load on the site. I wanted to place like a random code generator before someone can submit their registration. I am not sure how to code this or make it. Can someone lead me to a script for something like this?

Do not use STRING type of random code on forms it is better to use image captcha.

Also do not get a ready made code for this I will suggest you to learn it it is very easy to make captcha.

here is one good tutorial on simple captcha [codewalkers.com...] there would be many more GOOGLE IS YOUR FRIEND
