Can any of you guys who are already teachers recommend a course (or type of course) for breaking into the teaching English as a foreign language thing? How did you all get started?
While I'm living so close to London I think it would be a good idea for me to do some soft of English teaching course next year. Then I'll be all set for some more adventures

I know about the CELTA and TESOL. I like the idea of doing these in the UK, especially at a highly rated University here. My problem is that I don't think I could manage one of these at the same time as doing my job.
Are the online TEFL courses any good? I see that to teach in China you need a course that's 120 hours long. That's probably all I need, given I have two degrees and a very long resume.
