I voted to close unless + future: is it possible as a possible duplicate of the question Why must the future tense not be used after 'unless', which had been asked less than twenty hours previously. And I thought it better to keep the conversation about this usage at one place instead of being at two places ("sprawling" across two possibly duplicate questions).
Yet, now I notice the "duplicate notice" at the second question, which states:
marked as duplicate by pazzo, ColleenV, Nicole, StoneyB 16 hours ago This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
Ostensibly this is exactly what user5577 did. He/she asked a new question because the existing answers did not fully address his/her (further) question on the matter.
A concern is that referring user5577 back to the question (and answers) that initially caused 5577 to ask a new question does not actually service 5577's needs--unless, I guess, other or more comprehensive answers are added to the first question.
Is there a way for user5577 to indicate this, other than the seemingly sensible path of doing exactly what 5577 did: ask a clarifying question? What else could 5577 have done, given that he/she is a learner?
