how to track Google analytics dynamically generated usernames in goal conversions
<p>Currently am working on a site called sharedemos.com </p>

<p>Initially user lands on home page www.sharedemos.com then goes to <a href="https://www.sharedemos.com/sign-up" rel="nofollow">https://www.sharedemos.com/sign-up</a>   </p>

<p>then after signup a subdomain will form for every user like username.sharedemos.com/dashboard/library/      </p>

<p>It will generate new username for every user as a subdomain and I want to know how to track this as conversions in goal conversions. </p>

<p>What type of regular expressions I should use while creating a goal.
Please give me step by step explanation.</p>
