Question regarding parent threads that were not moved to the new forum

I actually came in this morning to post this question on the existing thread regarding the topic of the new forum, which I see has been locked. I find that confusing as I thought this was the place to discuss such things. Perhaps I missed something.

My question is it seems not all longterm, ongoing parents groups were moved and I’m wondering why the decision to leave specific groups on the regular parents page, such as “3.0-3.3 (GPA) Parents Thread (2013 HS Graduation)”, “3.0-3.3 (GPA) Parents HS Class of 2014”, or “Colleges for the Jewish “B” Student”. I think these are all wonderful threads, but as ongoing parent threads, not new topics that cycle through moving on for new topics, which I thought was the aim of clearing up the front page, why were these selectively left?
