I saw some call-to-arms post that got me excited for the free internet and set it up on my parents' residential service.
You can imagine the fallout. No permanent damage though.
It's not hard at all.

No. Your relays won't be trusted with significant amounts of traffic until they've been up for a few weeks.

This is extremely old. I am aware that the Tor project tries to keeps their defaults sane for any use, but someone has checked that the configuration here is still valid for this use?
Also, running tor as a root is bad idea, I don't think the client allows you to anymore (or at least warns you)
in the us, entirely legal. you may get law enforcement knocking on your door with questions, from time to time.
best to do it as part of a non profit or other organization, and being open about running a node, so that law enforcement/etc knows what they're dealing with
If you host an exit node on your home internet connection, the daily thing you will struggle with is not law enforcement, but rather the fact that your public IP will be blocked by most big websites to the point that simply browsing the web will become a pain.
Or the FBI setting you up and jail you for 3 years
Not to fear monger, in fact, the more people run exit node the harder it will be to go after individuals.
