[tor-talk] New Signatures after using gpg?

[Big Momma]

I am using Ubuntu 10.04 and have the following line in my /etc/apt/sources.list

deb http://deb.torproject.org/torproject.org lucid main

I then followed the instructions here

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

Why are there 3 new signatures?  What does this mean?  Thanks. 

gpg --keyserver keys.gnupg.net --recv 886DDD89
gpg: requesting key 886DDD89 from hkp server keys.gnupg.net
gpg: key 886DDD89: "deb.torproject.org archive signing key" 3 new signatures
gpg: no ultimately trusted keys found
gpg: Total number processed: 1
gpg:         new signatures: 3
