  First results from high-resolution coronal spectroscopy with the {\it
XMM-Newton} Reflection Grating Spectrometers (RGS) are reviewed. Five stellar
systems (HR 1099, Capella, Procyon, YY Gem, AB Dor) have been observed. The
emphasis of the present paper is on overall coronal structure. Elemental
abundances in {\it active stars} are found to be `anomalous' in the sense that
they tend to increase with increasing First Ionization Potential (FIP - i.e.,
signifying an inverse FIP effect). Coronal densities are measured at levels of
a few times $10^{10}$ cm$^{-3}$ for cooler plasma, although there are
indications for very high densities in the hotter plasma components.
