If you need help "check" the "Show Help" checkbox which is to the right of the Region / Country selection block and the help information will be shown in yellow.
Similarly "uncheck"ing the box stops the help information being displayed when required.
Currently, the help on or off status will not be remembered between visits but that will be changed in the next few days for registered users.
In respect of Registering, we never send unsolicited emails and we never share registration information, so your information is secure.
If you choose to subscribe to a Discussion or a Topic, Bird Id (and only Bird Id!) will send you notification emails of new topics or posts and you can switch this off should you ever wish to.
Any such emails will come from Webmaster@ either BirdId.co.uk, BirdId.org, BirdId.eu or BirdId.org.uk depending on which website you have logged into.
