There are two ways to create a Cometdocs Account and both ways are completely free and easy.
Registering via email
The first way to create an account is by submitting an email and password.
Click on the Create a Free Account button in the upper right corner of the page.
The last step requires a confirmation of your registration through clicking on a link that you will receive in the registration email that will be sent to the address you have given.
Registering via social media
The other way to register is to log in with your Facebook, Google or Skydrive account. Click on the Log in button in the upper right corner to do so.
Choose the account you want to log in with, enter your account data if you are not already logged in to that account, and then authorize the application. This will get you logged in directly. However, if you want to log in this way, you will have to repeat this process every time you come to the site and want to log in.
If you are signed in through the social media app and realize that you would prefer an account created via email, just click the Register a Password button to initiate that process from your Settings menu. After registering a password, you will be able to log in with your new password and the email you use for Facebook, Gmail or Skydrive. You can change that password from the Settings menu at any time.
If you want to revoke permission from the social media apps to your account, you will have to do it directly from your Facebook, Google or Skydrive account.
