Main Objective: improve the registration process on the site.
Situation: we currently have a one page registration and an confirmation email.
What we want:
1) make a step by step, page by page registration process. Users necessarily need to fill the first page, but other are optional an can be completed later (there is a Call To Action on the home page for that purpose)
2) check with Ajax script on the registration page the username, the email, etc
Note: we have examples on other pages for these
3) Our current confirmation email will now send reminder of user name and Password. The main task here is to significantly optimize it so that we don't get block by mail servers (we currently have confirmation email in place and A LOT of mailing to get to our users because they are blocked).
