Sounds like: "I've fallen and can't get up."
First, check that you're entering the correct username and password (with the same uppercase or lowercase letters and numbers). Your Activation Email has the "username" that you entered. Didja' save it?
If they're okay, then:
Does your account need activating?
These boards require that any new registration is activated, by the sender (you), before you can log on. You were sent an email as soon as you registered.
(The activation system is used to reduce the possibility of rogue users abusing the board anonymously. )
Did you get the Activation Email?
If you did not receive the email, then check that the email address you submitted is valid. Is our email sitting in your "junk" or "spam" folder?
Did you provide a working email address?
Is your email box full or over limit? Are you getting other emails?
If you are sure the email address you used is valid, you might try registering a second time.
If that fails:
Email the board administrator: webguru at tourexpo dot com (to avoid list-harvesting spammers, we've spelled out "@" and "dot".) Pls allow one full business day for a response.
