You did great. When a baker posts to confirm handoff with you (they will likely reply to your dough post), reply back to them to confirm handoff with them. I will check to see if baker has a history of baking here, but I'm not confirming the handoff, just checking to make sure a shill isn't reaching for the dough. Just hang tight and a baker will respond to you. Be sure to link this OP on the previous bread for ease of navigation.
Congrats on first bake. Have a good night, baker.
