Couponic changes

Hello, I have a website, built on Couponic from Uniprogy in 3 languages and need the following changes: 1.) On 4 pages to add: Create mandatory check-box with text and link as in 1.1.1 with same page position. Put under button "Subscribe" : All fields marked with * are mandatory. 2.) Establish a mechanism to cancel the service in the user's private area (My Stuff) via a link (at the bottom) of the tab "My Account". Link to "Cancel my account". Once the user clicks "Cancel my account", redirect to a new page with a text along with cancel confirmation button. 3.) Text to include in the e-mails which are send: user registration confirmation, modification and password reset. 4.) Add in the menu a new point "Register" (left of “Sign In”) for new users and which links directly to the existing registration form. 5.) Establish the ability to manage the subscription of the newsletter at the user "My Stuff" thus offering the user the possibility of signing up for a new category and / or city as well as the ability to unsubscribe from a newsletter on the website itself. I have all text in the 3 languages. Only experienced programmers. An advantage if you have worked with Couponic. Regards
