This area of the website is essentially an archive of all current and past posts to which it has been possible to assign a category. These are quickly reached by selecting one from the pull-down list but the majority of them also mirror the Signal groups that we’ve established – these are used for more instant comment and feedback.
It is almost certain that the topic categories will expand over time, and the website will try and keep the Signal groups in step with these changes and vice versa.
However we also use Tags to further describe our posts and these are of greatest use when using the Search form in the Menu bar.
Hopefully a combination of browsing by Category or searching by Tag will find the information you require.
