Okay, he's right, you can use the debug console, but I personally like using the conf file.
Here's how.
Nautiluscoin.conf Locations:
On Windows:
[DriveLetter]:\Users\
username\AppData\Roaming\Nautiluscoin\
[DriveLetter]: Most commonly C
On Mac OSX:
/Users/
username/Library/Application Support/Nautiluscoin
If it doesn't exist, it is safe to create one.
Inside the Nautiluscoin.conf you can place this:
addnode=178.33.39.168
addnode=94.23.29.195
addnode=176.9.63.136
addnode=54.186.223.183
addnode=54.187.101.97
addnode=74.208.230.160
addnode=184.155.218.183
addnode=71.227.74.98
addnode=188.194.8.82
addnode=109.201.154.157
addnode=184.155.218.183
The first three are the ones posted above, the last ones are the old ones, this should also prioritize the nodes as well. According to Bryce this proof of work move is definitely moving NAUT back to the 60 second transaction times :-) which is great.
