How can I add a user in the account and provide this individual with his/her connection information?

A user may be added in your account under  Administration => Users > Add a User.

1. Make sure you provide an e-mail address for your user.
2. Specify his/her account level rights (in the “Access Rights” section of the page).
3. When you’re done setting up your user, you might want to check the “Send connection information to the user” checkbox prior to clicking on “Save”. This way, an e-mail containing the account login page web address, the user’s username and a link to reset his/her password will be sent.
