Trans woman here, the thing that makes me most welcome is these little moments when my gender is subtly aknowledged without making it the sole centre thing that I am trans. An example of a situation I had recently, at the local bikekitchen, was a guy telling me that even if I don't know how to fix bikes I can still help, for example in the kitchen. And immediately he was like oh damn maybe I should not tell the woman to go to the kitchen, or some cariant of that, cant remember what exactly he said.
