If I have a question that is Unix sysadmin related. It's not clear to me whether it should go to serverfault or unix.stackexchange.com. Is cross-posting acceptable? The specific question I have in mind is 183337.
Since unix is beta at the moment, and we can't move questions there until it isn't, I believe cross-posting is permitted.
Your question prompted me to ask this: Could Appropriate Tags Cross-Post to Relevant SE Communities?
