OK, some explanation of these strange email addresses maybe required. They are displayed like this to try and avoid spam. As you may know, software robots trawl the web looking for email addresses in the format 'user@domain' or for the 'mailto:' tags in the actual code of web pages. This obscuration is an attempt to stop this happening. The address elements in the 'mailto:' tags are encoded as well.
So how do you email us? Simply replace the [at] with an '@' symbol and the [dot] with a "." and lose the spaces. This will give you the email address. Alternatively if you are viewing this on a web site, click on the links to open a pre-addressed email.
