Description	Modifications of edge localized modes (ELMs) with resonant magnetic perturbations (RMPs) in H-mode plasmas have been achieved in DIII-D, JET, JFT-2M MAST, NSTX and TEXTOR including (i) suppression of ELM energy losses with internal coils in DIII-D, (ii) mitigation of ELM size with external coils in JET and with internal coils in DIII-D, MAST and TEXTOR, and (iii) pacing of ELMs with modulated RMP pulses in NSTX and DIII-D. The experiments confirm that the island overlap width condition, used to guide the design requirements of ITER RMP coils, is not sufficient to assure ELM suppression in multiple devices. They also indicate that the L-H threshold power increases when RMP fields of sufficient amplitude are applied during the L-mode phase of the discharges. For 2011 and beyond, upgrades of the internal RMP coil systems are underway, that will permit greater variation of RMP mode spectrum to test ELM control physics models.
