A number of people have reported difficulties logging in to this forum.
At first login they get rejected . . . "too may logins".
They are then requested to log in again and enter the "CAPTCHA" which isn't actually a CAPTCHA but a simple question concerning the title THE SIGNAL BOX.
Login is then successful.
If you still cannot login I will need to change your password, please contact me by email or PM. If you don't know my email, go to http://www.signalbox.org/ and click on "Telegraph the Signalman".
Apologies for this inconvenience - I am currently trying to establish the cause.
