animation career events / NABS

I am trying to get in contact with, preferably London based, animation companies. I would like to attend some kind of events where I can talk to people from the industry and make contacts with them. Does anyone know if/what there are any events/fairs coming up in the next few months?

Another thing. Someone I know who works in the similar industry told me about the charity called NABS. I have been trying to find their offices online but don't seem to find their website! Does anyone know URL of NABS website?

Thank you in advance for your help!!
