I was wondering if it was accepted. In my case, for instance, I asked a question in other SE site (astronomy) that would be also on topic here. Unfortunately it didn't get much attention since that site is smaller. I was wondering if I could ask it here too. I've read the FAQ and it doesn't seem to mention this, so I don't think this would be a problem, but I want to be sure.
If it is OK, should I delete the other question first or that is not necessary?
