If you want to register with the teachers forum you'll be asked for your e-mail account.

Teachers board sends you an e-mail with a link to confirm your registration.

Unluckily this e-mail almost certainly ends up in the junk-mail folder.

So after registration check your junk mail folder for something that looks like this

(teachers board-----Your registration to Englishteachers)

You'll have to confirm your registration before you can log in.
