First of all, thanks for your interest in running a relay.

Of course you are always welcome to ask your questions on here, on #tor
irc channel or via sending an email to help@xxxxxxxxxxxxxxxxx in case
it's a private question that you don't want the whole world know about.

Well, it's more about how many "public IP"s you have than the number of PCs.

First you need to make sure your ISP is okay with receiving incoming
traffic.

Then, I'd suggest installing a fresh Debian on your PC.
You can google around to figure out how to install debian. It's fairly
easy. Here's a short, simple guide with screen-shots:
http://debian-handbook.info/browse/stable/sect.installation-steps.html

Then all you need to do is following these steps to install latest
version of Tor on your system:

https://www.torproject.org/docs/debian.html.en#ubuntu

Then open terminal and type:

sudo nano /etc/tor/torrc

and add the following lines to your torrc file, note you can change
ORPort number to whatever port you want (just make sure that port is
open in your firewall/router), pick a cool nickname for your relay and
add your contact info:

RunAsDaemon 1
ORPort 9001
Nickname name-of-your-relay-goes-here
ContactInfo your-contact-info-goes-here
ExitPolicy reject *:*

Press crtl+o then crtl+x to save the file and exit the editor.

Then you need to restart Tor using this command:

sudo service tor restart

Now your relay should be up and running.

> Questions:

Not if you become a non-exit relay. The "ExitPolicy reject *:*" line is
for that purpose.

you need to update your debian once in a while. the update process is
fairly easy. you can even automate it if you wish.

you can either use the interface or open terminal and type:

sudo apt-get update && apt-get upgrade -y

do this at least once a week please.

> 3) Will I compromise the anonimity of Tor users due to my lack of technical skills while running a Tor relay? I don't want to do more damage than good.

Nope. only encrypted traffic goes in and out your (non-exit) relay.

> 4) Can I throttle down the bandwidth on my Tor relay(s) when I need it for my own personal machine? I don't want to disrupt the Tor net.

yes, you can. read your torrc file located at /etc/tor/torrc to figure
out how. but please have it in mind that the minimum bandwidth for a
relay is 100KB/s (800kb/s). If you don't have that much bandwidth, you
may consider running a bridge instead of a relay. bridges consume much
less bandwidth and help censored users access Tor network.

I hope I've covered all your questions.
