I have noticed a sharp increase in brute force attacks on the website lately where people try to guess account usernames and passwords, so I have introduced some more security to protect your accounts.
Repeated failed attempts to login will result in your IP address being blacklisted temporarily and if you make more failed attempts after the temporary ban is lifted, your IP address will be permanently banned from the site.
If you are having problems remembering your password - use the Forgot Password link on the login form.
