William, I agree with you about the maturity and active community associated with commons math. I noticed other commons project are not as active.
Moving to a top level project, in my own opinion is valid, since the math topic covers a big area, unlike other projects in commons where they solve an focus on specific problem. So beside the visibility (which is enough for me), what other advantages do we get ?? By the way, even staying as we are under commons, does not really prevent us from building these subprojects. We may get more contributors if we go higher level, but not too early to consider these subprojects under commons.
