So, [here](https://superuser.com/q/700651/279815) is the question. I think this question belongs to [database admins](https://dba.stackexchange.com/) but when I try to flag it, only meta, stackoverflow, serverfault, webapps and android stackexchange sites appear. Therefore, I flagged as it needs moderator attention and got declined. 

![enter image description here][1]

What am I supposed to do here? Or any similar situation where the to-be-flagged question does belong to other stackexchange site which does not appear on the list provided?
