If I review a question and want to close it as off topic, I run into a dead end:
For example, the question is about Android, with no explicit or implicit relation to Unix or Linux.
There is no problem, I have to mark it as plain "off topic" or as "off topic but belongs to Android". All is perfectly fine until I run into the list of sites I may indicate it belongs to. There are only two sites listed, and there is no "others" field.
What should I do at that point?
Why is it like that?
