You can add them with addnode= in the conf file. But I just ran with the default seed nodes and it worked out of the box. Are you using the most recent version? I think most of what I'm connected to is things like:
5 Host: node2.mercuryminer.com
DNS Seed: 52.68.138.229
6 Host: node2.nexusminingpool.com
7 Host: node2.nxs.efficienthash.com
Also, for faster answers, there are a lot of people in the slack channel who can help with questions like this. The response there is 10x faster than in this thread.
