I've been meaning to raise this for a while, and it got to me today.
I'm sure previously you used to be able to vote to close, choose "more suitable for another site on the SE network" and select the other site. However, when I do that now, all it shows me is meta.travel.SE. If I want to say, vote to migrate a question to cooking, it isn't giving me the option. And I'm sure it used to, no?
