With a major software change, such as what we're in the middle of, there are things that you'll have to, one time only; like activation.
I've changed the email address for you.
Your next steps are as follows:
1. Clear your cache and cookies. The cookies have been changed, so in order for you to be able to initiate activation, you have to clear the old cookies out.
2. If your password is LESS than 8 characters, it must be reset. You'll generate an email from the reset link, and then change your password from the link emailed to you.
3. Activate your account.
I've linked to directions for both the cookies thing and for password reset and activation. Once you click the link to activate, this logs you in. Remember that all member functions are initiated from the central member portal. The ability to access these functions from the rest of the archive (i.e. you're in the books subdomain). While the coding is still in progress, there are some things which are display only, such as the old profile and tools accessible from the other subdomains.
