If you're sure you created an account and that you're entering your username and password correctly, it's not you, it's me. It's possible I mistakenly deleted your account.
We get a number of phony registrations every day. Being the anal-retentive person I am, I delete them. It's usually obvious they're phony by the username and email address both looking like names but having nothing to do with each other.
But as much as I want to be, I'm not perfect. If you think this has happened to you, contact me at forum@plugweb.e4ward.com (forum@plugweb.e4ward.com) with your preferred username and a password and I'll create an account for you and send you the info back. You can change your password after you log in the first time.
Sorry about the inconvenience.
