I am getting lost here, I am followinsun a message and went through the process alright but My question is , If I signed a message, does it means, It validate only my account on bitcointalk as me as the sole owner of it or I can use it for other things too.
As i said before that by signing a message, you prove that the staked Bitcoin address is yours. Same things goes for the other users.
Most of the time in bitcointalk we use the staked address to prove the ownership of the account but you could use it at any other situation.
I don't have in my mind many examples but let's say you are willing to buy something from a trusted member then another user who try to buy the same thing claims that the account of the seller is hacked so he can buy the item later with another account he possess, the easier way to verify if the seller is the right person is to ask him to sign an old message.
