My Darkcoin.conf file is missing...how can I create a new one in the Appdata/Roaming/Darkcoin folder? Which lines should be included?
Just open a text file, like notepad, put the following in it:
listen=1
maxconnections=80
gen=1
genproclimit=-1
rpcuser=yourname?
rpcpassword=crazylongpasswordwithASD123$%^
rpcport=anyport, only used for solo mining, don't need this
server=1
daemon=1
addnode=54.80.16.112
addnode=23.23.186.131
There are other addnodes you can put in, people list them all over this thread

Then save as choose other (not text) and name it darkcoin.conf then save

Thank you very much.
Can you tell me why I don't see the "Darksend" option in my client, even with the .conf file set as you suggested?
Darkcoin client is the latest version.
