I'm not sure how to add nodes, I've tried to use the "addnode=81.21.164.231:8087" and "addnode=184.72.95.126" but both returned the "Method not found (code -32601)" error.
Wanting to move the 808's I got at POSWallet before the delisting.
You can always try creating a .conf file for the wallet at %appdata% in a Windows running machine.
