Well, we're drifting from ABBA, but it's an interesting drift.

A parallel which might be worth looking at if anyone is into it is the lanuage Swahili - the point is that, up until recently anyway, this has been no one's first language. A bit like Esperanto, except that it happened organically, and is used by many million of people as their way of communicating.

As you say Joerg, maybe there could be a thread about this kind of thing. (And why are you still a GUEST instead of signing on as member?)
