There is also a website called QualityGal which also accepts non-US. But as far as I can tell they are not such a huge website and don't have so much work available. That is only what I have heard though.
So those two and IB are the ones I'm most familiar with at the moment; more opportunities keep popping up though. Keep your eye on freelancewritinggigs.com and
ONLINE WRITING JOBS - Freelance Writing Jobs.
The answering-question service ChaCha did not accept US writers when I asked a few months ago, but it sounded like they have plans to accept nonUS writers in the future.
There is also a site called writerfind, and forums called accentuatewriters and absolutewrite. Might find some more leads there as time goes on. The information on the absolutewrite forums has helped me to also feel confident enough to think about attempting some freelancing in print, or other kinds of writing/publishing.
Good luck!
