Get a new activation link sent to your email
Sometimes activation emails end up in spam or promotions folders. Check there first before requesting a new link.
If you registered more than a week ago, your link has expired. That's totally normal - just request a fresh one!
Make sure you're using the exact same email address you used when registering. Email addresses are case-sensitive.
If your account is already activated, you'll get a message saying so. Just try logging in with your username and password instead.
