No. The 'constructiveness' of your posts is largely irrelevant and if you don't post in each activity period you will lose those points forever. You'll be a Senior on the 3rd of March providing you post in every period up till then.
You meant all of my posts are futile?
I'm not sure what you mean by that. It would be futile posting many posts in an attempt to gain Senior status as it wont happen whether they were constructive or unconstructive posts. If you miss posting in the periods you miss out on those points forever and the only way to rank up is collect enough points in the future.
Oh, now I got it, and sorry I misunderstood... I thought something else, but... Thanks for clarifying it in a kind manner...
And yes, I ain't posting to get Sr. Member status as I knew that I won't get it, it's just that I wanted to confirm it and so I asked it here as you are the staff member and now, it's all clear... I will post more questions in future if I have any...
