How to Get an Account
Move Account Info Uses Email-Address Logins.

Why email-address logins?
  • Users forget their unique "login name" or "handle" and create duplicate accounts.
  • Email-addresses are by definition already unique.

Login names (handles) will continue to be part of an user account. They will be used within the site to identify the user in situations where anonymity is an option (example: trackers, forums).

Login names will continue to work for login to the site.

Common user account dilemmas policy: A user account follows the user. A user account history includes company changes as well as other account activities. Due to licensing issues, download activity remains with a company. A user is never purged from the database, even if deleted, so that their history of download activity is always available within the logs of their company at the time.

Let us Move your account.

  • You have a Visitor account but your company now has a account on What should you do?

    Contact the Site Admin and request that your current account be moved to your company area. A company domain email-address will be required.

  • You work for a different company now. Create a new account under your new company?

    No. Contact the Site Admin and request that your current account be moved to your new company. A new company domain email-address will be required.

  • If you HAD more than one user account with identical email-addresses in August 2006, all but one was disabled.
    We are sorry if we disabled the wrong account. In most cases, users had a Visitor account as well as a company account of some kind. Our policy, in cleaning up for unique email-addresses, was to disable duplicate-email-address Vistor accounts as they have low access to features.

  • Confused? Problem? Contact the Site Admin. Thanks - Si2Admin

Process: Moving an account to a different "company"
