ESL, EFL, TESL, TEFL, TESOL, ESOL

What do ESL, EFL, TESL, TEFL, TELSOL, and ESOL mean? I've seen it a lot on this site, and I'm still not sure what exactly it means.

ESL = English as a Second Language
EFL = English as a Foreign Language
TESL = Teaching English as a Second Language
TEFL = Teaching English as a Foreign Language
TESOL = Teachers of (or Teaching) English to Speakers of Other Languages
ESOL = English for Speakers of Other Languages

The differences are not that great, and in some cases regional - ESL is more used in the US and ESOL in the UK and, I think, Australia, though both refer to learning the language in a country where it is spoken, while EFL is used for learning it where it is not spoken. If you can teach one, you can teach the other IMO.
