CMS Made Simple Forums

CMS version 1.0.6 with frontendusers
I am new to cms and need some help with coding. My website works ok, but I want to use user login coding to avoid spam etc.
I get theusernumber and passwortd request with the captcha request to type in, but i do not know how to code around this and have actions depending on the correct login or failure. Also I need users to register if they do not exist.
I am looking for some coding examples on how to code this into my content page. I have very little php experience, but can read code as I used to be a programmer when I was young.

for users to register themselves you need the 'SelfRegistration' module.

to display different content to different users, you need the CustomContent module.

and then, you need to learn the {get_template_vars} tag, and smarty at smarty.php.net/manual/en
