As you can see the software that powered the community has changed. With the change there are some subtle changes to the way you log in.
You can no longer log in with you username and password. You have to use your email address and password to log in.
This is done to secure your account. In order for a person to log in as you with username all they would have to do is know your username. They could then run a script attempting to find you password. Now they would need to know your email address. The only one that knows that is you and the software. Your email address is not visible to anyone except administrators.
If you are unsure of what email address you used to register or forgot the email address you used contact me and I will sort it out for you.
Thanks for understanding.
