I seem to keep getting my posts put on hold in various stack exchanges because it's "unclear what I am asking." How can I do better to prevent this? Specifically right now I'm asking about this question.
Edit: The linked question has been reopened.

I'm late to the party, so I have undoubtedly missed something. My two cents might be worth a little more than two cents though.
The problem was marked unclear when the basic parameter $n$ was marked as a real number. While it is possible to frame the problem this way (and assume $p_t$ is 0 for all but countably many $t \in (0,n]$ ), it is more natural and to me more clear to have $n$ as a parameter and $i$ vary over finitely many values. The question was closed before this parameter was changed to a natural, and reopened after this change.
I am not aware of your history on other fora. Repeating Gerald Edgar's advice, I recommend asking on the meta for forum X about a question that was closed on forum X. Although there may be a common reason, the different fora have different standards and thus you may need to "rub different colors of mud on your navel" to have the questions accepted.
Also remember: your question being closed does not mean it is a bad question. It means it was asked in the wrong place, or in the wrong way. Also, sometimes the close reasons don't always sync up with the whole community perception: this is a known flaw of the system, and suggestions for improvement are welcome. (Keep in mind, much of the whole community does not read your question.)
