Thanks but this doesn't really help me, I don't understand? I have one masternode, not multiple. I want to donate a portion of my rewards to the developers. Like I've said i looked for a post or explanation about how to do this, all over the forums, and I CAN NOT find it. I know these guys are busy, I know we're all busy, but someone is trying to donate money, it might be a good idea to show that person HOW to do it.I had the same question and found this post on doing donations with a multi masternode config.
And this is the link to setup multiple masternodes from one wallet.
*edit* Especially when that person is going to write a formal guide and make a how to video to go along with it, which would make future explanations easy for everyone.
