I flagged a post to be moved to another Stack Exchange site.
When I choose, "This question belongs on another site in the Stack Exchange network" the only choice I have is "Homebrewing Meta", which doesn't make sense... is this a bug?
Per this Meta SE post, it looks like only a moderator can move questions to sites not explicitly listed on that screen. I vaguely recall seeing on a previously that there's some kind of special way to get sites added to that list but I think it would need to be driven by need and relevance. For example, I could imagine us eventually getting Beer, Wine, & Spirits added there if we were frequently migrating questions there but questions intended for Stack Overflow are presumably less common here.
Regardless, I saw your flag at effectively the same time as your post here and was able to move the question without any problems.
