On my Gambio online-shop i installed a special customer group module which lets customers choose theyr customer group when they register for the Webshop. But 2 of the 3 customer groups need special fields in the login form. If you click on one of the special groups a new «Link» field should be visible in which the customers should post a weblink and on the other special group there should be an «Attachment» Button that lets the customer attach a file. Wehn the make a login with these 2 special groups there should an email be sent to an adress with all the login-information and the special fields.
I also need on a special separate content page a customer creaton formular which puts the customers in a special customer group (that should be manageable with the new customer group module) and a login field which checks if the customer is already registered in this special group and redirechts them to another page.
