Conclusions

ĄThe thermal Sunyaev-Zeldovich effect has major effect on the CMB spectrum at large angular scales, but is easy to correct for. The kinetic Sunyaev-Zeldovich effect is much harder to correct for, but is very small.
ĄExtragalactic radio sources make small but ultimately unimportant contributions to CMB up through large angular scales (but are interesting in and of themselves).
ĄFar-infrared sources deserve more study, but will also probably require only minor corrections to newer measurements of the CMB.
ĄPlanck and MAP will answer many of our questions about the CMB, and should be able to bypass most foreground sources.
