I have installed the user-info block and it works fine except that the login in section does not include the security code part, therefore, when someone tries to login, it wont let them because they didnt put a security code in, even if their pw and user name was correct. It then takes you to the login wrong page, and asks you to relogin, which you can do.
here is the site if youd like to look for yourself
