This question already has an answer here:
Now we've graduated from beta, wouldn't it be time for us to set our migration list?
I would propose:
- meta.security of-course
- math / theoretical.cs / stackoverflow
Does the moderators have some feedback on this in term of statistical of previous migrations?
This query seems to indicate that only 4 migrations took place. 2 SF, 1 SO and 1 SU.
