Few Rectifications in Magneto Website

Hi techie's I am a developer too Right now I am stuck in a very small problem with magneto I have a magento based store and it creates a subdomain on my server everytime a user sign up for a new account and that subdomain can be accessed Like [login to view URL] or [login to view URL] Right now what problem I am facing is 1. New Account is created 2. subdomain is automatically made 3. but can not be accessed they can be accessed like [login to view URL] but can't be accessed like [login to view URL] now there is no htaccess rule which can translate urls like this My website uses https:// My second Problem is I want you to change signup process in such a way that duplicate accounts can not be created with a single email i need this to be done with ajax and jquery so that when user inputs an email which is present in database he is given an error right next to the email input field Low Price and Non Generic Bids Will be entertained Please right "I am magneto Developer" in you proposal Happy Bidding I will be back in 5 hours and choosing one of you :)
