Welcome. I'm still really new myself. Only been at this 2 years now and not nearly as many days a season as many on this site (I'm not so secretly jealous of them all).
My first experience was rough too. Almost caught a concussion coming down a green too fast and taking some BAD tumbles. I had taken one lesson taught by a kid that couldn't have been older than about 16 who shouldn't have been trying to teach anyone. Tried to teach me and my cousin the foot flexing technique (press down on this toes while lifting that heel, then lift this toe and press that heel). After that I have pretty much been taught solely by way of watching Youtube videos and reading comments on sites like this. Its helped me out enough to be able to comfortably ride down any blues I've come across in the Vermont and Maine resorts I've been too.
