I asked this question on superuser, but I think it is more appropriate to ask it on stackoverflow. Since it's my question, I can delete it from superuser without any moderator privileges and just re-ask it on stackoverflow. However, that doesn't seem to be the trilogic way. Is there any way for me to force my own question to migrate from one site to another?
Nathan, I honestly think that the question you've asked is a question about application configuration, and that Super User is the appropriate site for it. It's well stated, and it's exactly the kind of question I think Super User is for.
Now, the applications you're configuring do have some use in programming, and the SO community can give you answers faster than SU can. That's not a great reason to post it there, IMHO, but I can't stop you.
So I won't migrate that question for you. But if you want to repost to SO, go ahead -- if the SO community migrates it back to SU, the two can be merged together, and it's quite likely you'll get answers on SO before the question gets migrated.
Please do not delete your original SU copy.
Edit: On the topic of mechanisms a user can use to effect a migration on his own, there are three:
One or both of the first two options may have a minimal rep requirement, but I get both options on my SO questions, and I've only got 300 rep there. So they are available, if not to all questioners, to all but the newest users.
While the process of moving a question over by the person who posted the question seems like a nice feature, in reality it would be (and should be!) used very little:
Given that the author can usually delete the question and re post it, there's no need to create this function.
The only situation where it might be valuable to have this function is if the author posted the question thinking it fit best on X, but after a few answers pointing out solutions that came from another realm, or helped define the question better, the author came to a new understanding about the question and decided it would be better off someplace else.
In that rare instance, especially when an answer has been upvoted and the question can't be deleted, flag the question for moderator attention and use the comment box, "Please migrate to Y."
I don't think that a feature allowing users to do this would add significant value to the site.
Just flag it for moderator attention stating that you think the question would be better suited on Stack Overflow. If he agrees, he'll migrate it.
Or better yet, let the community act. Of course, letting the community migrate questions works better, or merely faster, on Stack Overflow than on Super User.
Users can be wrong in which site they ask their question on. That means they can also be wrong in which site they would choose to migrate it on.
As told, it's not possible currently, flag a moderator. I don't think this is a feature which should implemented, though, as it would be easy to migrate a question on any site then, and spam all the trilogy with it, just for fun.
This operation should remain only for moderators and 5 votes from 3k users (and the later is already abusing it).
