need for plugins to register user in external sys

Hi All,

I need advise and help for developing a CB plugins to allow new register user in CB to also register in a third party system.

Since I am not a programmer, I browse through the API doc and helloworld plugins, but i have no idea how can i start doing it ?

I have the web services API for this external system allowing me to send via xml link to :

1. Create a new user
2. To update user password or email
3. To login and authenticate

I saw there is CB event such as onAFterUserRegistration, onAfterLogin ...etc, but how do i go about implementing this plugins ?

Advise and help really appreciated !
