First, check that you are entering the correct username and password. If they are correct, then one of two things may have happened:
A. If your age is 12 or less (you clicked the 'I am under 13 years old' link while registering) you must follow the instructions that you received by email to activate your account, or
B. If you do not have the email providing an account verification link, be sure that you entered a valid email address, or that your email has not been caught by your spam filter. If you are sure that the email address you used is valid, contact the firstname.lastname@example.org
ABA "Bell Talk" forums require activation so please remember to click on the link sent to you in the verification e-mail that you receive right after you register.
