Once your registration is complete, you will be able to login to the site through the "Customer Login/Logout" tab at the top, right-hand corner of your screen. To do this, clicking on the tab will show you an area where you can enter your username and password before clicking on the "Login" button (or hitting "Enter" on your keyboard).

You've registered but can't login.
This happens if your username isn't recognized or the password you've entered doesn't match the (encrypted) password associated with this username. The simplest thing to do is to click on "Lost Password?" in the login/logout tab. This will bring up a short form in the middle area of the screen asking you to fill in your username and the e-mail you believe is registered with this username. Once you've entered this, clicking on "Send Password" will either send you a new password or will show a message indicating that this user information couldn't be found. If the latter happens, please contact me and I will try to find out what's going on.
