Joomla sign up form with jomSocial

Hello Freelancers, 1. I am creating a custom joomla signup form, however I only need this form to send an activation code to the user's email, that's all. For someone who knows Joomla very well this shall be a 10 minutes task. 2. The user gets an email with the activation link, once the link is clicked the user is activated. Just to make sure you read all of the requirements, and you know Joomla very well, type "I KNOW JOOMLA209" while bidding or sending a PM that's all thank you very much.
