Effective collision strengths for electron-impact excitation of the N-like ion Sx are calculated in the close-coupling approximation using the multichannel R-matrix method. Specific attention is given to the 10 astrophysically important fine-structure forbidden transitions among the ^4S^o, ^2D^o and ^2P^o levels in the 2s^22p^3 ground configuration. The total (e^-+ion) wavefunction is expanded in terms of the 11 lowest LS eigenstates of Sx, and each eigenstate is represented by extensive configuration-interaction wavefunctions. The collision strengths obtained are thermally averaged over a Maxwellian distribution of velocities, for all 10 fine-structure transitions, over the range of electron temperatures logT(K)=4.6-6.7 (the range appropriate for astrophysical applications). The present effective collision strengths are the only results currently available for these fine-structure transition rates.
