And yes I'm still new to this signed message thing, and i got a question, does signing a message with said address need the private key?

Of course, you need your private key to access your old wallet for sign message. But if you've never posted that address or PM sent that address to someone in the past, I think maybe your request will be rejected. So the bottom line is that any bitcoin address you have used in the past on forum will serve to prove you are the real owner.

Yes that is true that private key is needed to sign a message, but Redoubt should know that the private key is not included while signing, what that are included are just 1. The bitcoin address for signing the message 2. The message that will be signed, after these has been filled, the user can click on sign message, the message will be signed. Not all wallets sign a message, not all private keys wallets also sign a message, there are few ones that do it, like electrum and coinomi.
