Crawl, advice for beginners?

This looks like a nice forum. I'm from abroad (the Netherlands) so Englisch isn't my mother language. I recently started 'learning' the crawl and I could really use some :help: I can generate quite an acceptable speed with my arms but I do have 3 big problems with my crawl right now. 1. I swallow way to much water. This often happens right after inhaling air. I am under the impression that I stop inhaling before I turn my head and I start exhaling once my head is back under the water surface. 2. I can't generate any speed with my legs, not even one tenth of a meter per second.:( Right now I just move my legs up and down, I keep my legs and feet straight with my toes extended. Since I don't get any speed and I have strong legs I must do something wrong. 3. I don't know how the arms and legs should work together. I hear 3 different versions: - don't pay attention to the legs, you will move them automatically to compensate - 2 strokes with the legs for 2 strokes with the arms - 6 strokes with the legs for 2 strokes with the arms What is indeed the best technique for the crawl? Thanks to anyone who gives me some good tips.
