Today I have found out that the maximum allowed frequency of posting new questions is 1 question in 40 minutes across all Stack Exchange communities taken together.
Given that there are many questions on different topics on my mind, I could of course take notes and wait in 40 minutes intervals reading around or doing other things which sometimes leads to more new questions. Or I could try not to forget the questions and get anxious.
But, maybe it is possible to implement a queue feature, like I file a question, give it a processing priority "any time". This would relax me a lot as SE user.
p.s., Is there actually any level of achievement to overcome this limit somehow?
