The spacing glitch sounds like the input handling is trimming or merging tokens, so clicking between the words is probably just a workaround. On the interface point, tighter layouts can work once you're used to them, but if buttons sit close together it hurts scanning and tapping. I'd second spacing it out over copying another site's layout wholesale. As for the email question, that depends on how the posting permissions are configured, so it's worth checking the sign-up or account settings rather than assuming.
