I voted to close this question on programming, and wanted to vote to send it to StackOverflow, but noticed that I couldn't choose to do that:
Notice that I cannot click "Vote to Close" on the second screen unless I select the meta site, which is not the appropriate site for this question. Is there a way to add either a list of .SE sites, or be able to type in a site, or at least leave it blank so it can reflect that it should be on another site?
That question would have gotten closed on Stack Overflow.
It is a bad question - OP is asking people to do his work for him and would have gotten shot down rather quickly.
That is orthogonal to your question though - there are up to 5 slots for migration on every Stack Exchange site - sites still in beta only have a migration path to their child-meta (for obvious reasons), but no others.
Why is that?
Because it is not clear when a site starts what the best 4 other options should be - this takes time to find out as off-topic questions accumulate and people want to migrate them.
Now, for this site, I doubt that Stack Overflow should take one of these slots - how often would programming come up here? Not often, I suspect.
It is better to use these slots for sites that will actually make a good migration path - for topics that come up fairly often here but are not in the site scope but are in another site scope.
An alternate solution is to leave the proposed migration site as a comment, and allow the mods to do the migration (we can always do this, regardless of status).
