I've already made a donation, but I'd like to be more actively involved, without having to do a load of travelling (where I live is solid Tory, and I don't have a car). What is the phone app thing I keep hearing about? Making calls to target voters or something? I could spend my evenings doing that, or at my local branch. What're the options there?
Edit: sorry, repeating a lot of Dr Rocks questions there.
