Hi, and welcome back.
In order to get you activated under the new code that's being implemented, we recommend the following steps.
First. clear your cache and cookies.
Next, follow the steps outlined here exactly. You need to use the email account that was used to create your account. Please also note that sometimes your ISP will route our email to your Spam or Junk folder, so if you don't get an activation email, check there first.
Just to alert you, the center login fields are only used when you initially activate the account. After then, please use the fields in the upper right corner. We have a known bug with the center login fields.
If you have any issues, including needing to double check the email address used to create the original account, please email us at tos_team@adult-fanfiction.org and we can tell you what we have in our records. For safety, we do not recommend putting your email address here in a public forum.
