first problem seens when i click on register, your url is: http://www.fjordx.com/register.php3?SESSION_ID=
no session id??
second, just a preference, but you should have option select for united states, instead of hunting through tons of countries.
i was proud to see that you verify the correct birthdate. grats on that. however i entered 15/15/1115 and it worked ;o)
you have your $registered_users set to people waiting for confirmation as well.. don't know if that was intended though 🙂
your registration confirmation is from (unknown) -- might want to add a title to the confirmation mail.. it says: "Thank you for registering at . Your user information appears below. Please visit us often at . " so you might want to change that as well..
you should add values to all your submit buttons -- otherwise they just say "submit query" -- very generic.
your user_login.php script seems to be the problem. do not do this:
ACTION="user_login.php3?SESSION_ID="
just do this:
ACTION="user_login.php3"
and then learn howto and create sessions. and they will become transparent and you will not have to worry about sending them via the urls (not to mention it looks weird seeing a129387189bsd019238193373 in the url)
just a few things off the top of my mind. i didn't mean to totally pick apart your site. i just want to tell you what's up from what i spent five minutes poking around at. post user_login.php3 and we can help you figure it out.
cheers,
