If you wish to add some nodes to your silk.conf you can use these:

addnode=162.243.163.103
addnode=62.30.13.24
addnode=slkexplorer.silknetwork.org
addnode=82.73.172.120
addnode=91.220.151.240

For windows users you will need to put these lines in a file named silk.conf and copy this file in the:
C:\Users\...Your Account...\AppData\Roaming\Silk\

After you start the wallet you can also go to the Menu->Tools->Peers List
and if you see new ones post them here
