I'd like to commit to the new Scientific Computing proposal, but the page says I'm committed to the maximum of three proposed sites. One of the sites is in public beta. I really don't have any questions for it, or know any good answers. Although it's a topic of interest at other times, I'm just not going to be active on it for now, maybe ever.
It's basically a nice site to have around in case I need it someday, so I wanted to, in a sense, upvote or support it, but I won't be a significant ongoing user during beta. I have misunderstood the nature of commitment, perhaps, as a way of saying "yes!" to a good site idea.
Is there a way to "drop out" of that other site so I can commit to the S.C. proposal, which is of more current relevance and where I can be much more active?
