Since I'm not very invested in these sorts of big group RPs (and rarely even smaller groups) I don't know very much about them, and the admins hasn't told us very much either. I'm guessing that the universe roleplays are of such a big scale that a lot of commitment and pre-planning is necessary, thus the admins wants to make sure that those who are committed and has well thought out ideas will get that space so that those roleplays don't die as easily as they do in the other sections, thus they are planning an application form, which to my knowledge hasn't been completely worked out yet.
The admins have been very silent about it so far, so we don't know much about it. It's just to hope all the testings will be done soon so that they can continue working on it.
