There are lots that can be done, initiative is an excellent thing. Campaigning, politics discussions, etc., is one thing, but reaching out in the local community, investigating murders and assassinations in one's free time, investigating in the local community (and do keep yourself anonymous...), etc., etc., etc., are all options. Of course, one problem with that is how to spend your time wisely and also not fall into various traps and the like.

I thought about giving more direct suggestions, but the problem is that shills are everywhere, so partially revealing your hand is not a good idea, and partially trusting what "suggestions" there are online is not always such a good idea. And good suggestions are not always that easy to figure out.
