[BitMan94]

Not saying that i agree for segwit 2x, but im curious of how you singnal for segwit 2x? do i run a node for them? If so what node is segwit 2x support by?

miners signal for SegWit2x or any other proposal in future not users.
and they should do it with a version bit in the blocks they mine. this process is done with a BIP which makes that version unique to that proposal so everyone can follow it.

for this particular proposal which is also known as New York Agreement they have been doing a different thing. they add a little text in their coinbase transaction saying "NYA". that is kind of an unofficial support.

as for nodes, here is the client they have released: https://github.com/btc1/bitcoin
