Pointers to RT Resources

It seems there’s useful information about RT in many places,
some of them not easy to find. In an attempt to collect links to
information in one place I started a list of helpful resources and
posted them on the FAQs section of the wiki.

Please feel free to add to, remove from or generally correct my attempt
