If you want to join the LinkedIn Group, do please indicate what your particular interest in trade marks is, so that your application to join can be approved (this normally doesn't take more than a couple of days).

If you're planning to start a discussion, please phrase your discussion topic into the form of a question or statement that makes it clear what you want to discuss.  Note that, while announcements of change of address and links to websites containing factual or promotional information may sometimes be of interest to members of the Group, that does not make them discussions!
