Does only being allowed to post once every forty minutes include other SE sites? I was told that I cannot post a question for this reason - but I have not yet asked any questions on this site. What are possible reasons for this?
Also - is this a rule in general on all sites?
*Update - I tried to post this question and again got the message "You can only post once every forty minutes". Does this 'once' overlap with both the meta and regular site?
