I'm not sure if that's what they're still calling it, but some anarchists do this thing where they choose a place to squat (i.e., move in to an abandoned building, fix it up, etc) and use that as a base of operations for anarchist propaganda -- with the idea that eventually they're going to be run out (hence, "temporary"). But during that time, they set up a little mini-society that acts as an anarchist primer for the inquisitive.

And on the other side of the spectrum, I know an anarchist who routinely runs for political office, unapologetically, and won more than once on the local level. He's an interesting guy... has gone toe-to-toe with other anarchs who routinely accuse him of selling, and he responds tot he effect of "I've done more to stop the statists from screwing over my neighbors in one term of office than you ever will in your entire life." Only more colorfully, you see...
