Looking at this releases for windows: Are in any of these releases public exits on by default?
In his post @SamWhited assumed that they are off.
But looking at Point g of Configuring a Tor Relay:
If you want to allow others to use your relay for these services, don't change anything. Un-check the services you don't want to allow people to reach from your relay. If you want to be a non-exit relay, un-check all services.
So these bundles generate an exit policy by default?
I just feel a little panic because I'm, unsure weather i could have installed the bridge bundle a week ago instead of the browser bundle and that this could have resulted in an accidental public tor exit :-(
