Online job hunting

[hmpf]

Now I remember why I dislike online job seeking portals. They force you to choose one particular field of employment, from a very short list (ca. 20 fields) that invariably doesn't contain neither what I've done so far, nor what I could see myself doing in the future. How am I supposed to fulfil that requirement? Especially when I'm not really looking for a job in one particular, narrow field? I want my CV to be visible to potential employers who are interested in the "knows English and can type" side of myself as well as potential employers who are interested in the "knows how to work metal" side...
