Just to clarify, I've gone through the user set-up process (including the Captcha) using IE (which has Flash installed). I get to the point where I'm told to wait for a confirmation email. None has appeared (~24 hours later). ID I'm attempting to register is Dragon32. I've checked Spam folder to see if the email has been miscategorised, no luck.
Attempting to re-register with another account name and the email address used in my Dragon32 registration shows "This email address is in use"
Attempting a password reset on the Dragon32 account gives me the message that an email has been sent, however none arrives (but I didn't really expect it to having failed to complete user registration).
Apologies for previous double post and this one, I can't edit those posts to include this extra information.
