Running - how to improve your style!!

[lovetochat]

I really hate to admit this but I need some help with my running! It seems like it should come naturally but honestly, it doesn't! When I run, my knees seem to turn in so my legs (from the knee down!) go out. Does anyone else have this problem. Oh please someone have this problem!
How can I improve my running style? I don't really realise I am doing it wrong, it is just if I look in the mirror at the gym or if someone tells me (ie. laughs!).
