If a forum is configured to require email activation before login, an email will be sent to the email address provided at registration. Important account information, such as username and password, can be found in this email, as well as an activation link. Selecting the activation link activates the member's account and prompts them to login. If a problem occurs with the activation link, the email also provides an activation code that can be used to complete the process.
If a member attempts to login before completing the activation process, an error will be displayed noting that their email address must be validated. A Need another activation email? link is also displayed in case the email has somehow been lost.
