After registration, an activation email will be sent to the email address entered during registration.
If this has not arrived, there are only two possible causes:
The activation mail has ended up in the spam filter. Please check the spam folder in your mail programme.
The e-mail address used for registration was incorrect, so that the activation e-mail could not arrive.
If you visit the PFF pages and are logged in (but not yet activated), you will see the following notice at the top directly under the menu bar in the PFF:
Your user account is not yet activated. Complete the activation process in order to be able to use the full range of functions of this site.
Here you have to click on Complete the activation process. On the page that opens, you can enter the registration code manually. Since this is exactly the problem, you must select Request new activation code below.
Request activation mail again
To request the activation mail again, you must enter the user name and password you set yourself during registration on the following page. The field "e-mail address" can be left blank, in which case the activation e-mail will be sent to the e-mail address selected during registration. However, if you are unsure whether a spelling mistake has crept in, you should enter your correct e-mail address here again to be on the safe side.
The activation e-mail will then be sent. If it does not arrive again, it can only be because the e-mail has been filtered by your mail programme. Please check the spam folder.
