Very Newbie- Where do I add the addnode parameter

Very new to mining,
I have been trying to mine a very low difficulty static coin for a couple of weeks no... without success...i keep on getting an error where coin is not found with the "c=coin" parameter and error: coin/algorithm is incorrect when I use "c-coin m=solo". I was thinking to add the addnode parameter to see if this would help, but I have no idea where to add this parameter. Any help would be greatly appreciated!

1.) What coin are you trying to mine?
2.) What interface are you using to input your password arguements? This site only does Scrypt and X11 algorithms
3.) What type of mining hardware are you using?

I am trying to mine a low difficulty coin like Rabbitcoin
Bfgminer is my mining software
I am using 1 x Asic Scypt USB miner Moonlander 2

Configuration

bfgminer.exe --scrypt -o stratum+tcp://prohashing.com:3333/#skipcbcheck -u webuserlogin.1 -p "c=Rabbitcoin",d=128 -S MLD:all --set MLD:clock=756 pause

Thank-you in advance!!!

I tired on my L3+ to run Rabbitcoin and it is NOT working. Don't know if it is an issue with Prohashing or something else. Sorry

Thanks, very much appreciated
