I can understand the admininstrators not wanting to publish what 'sufficient' means, as the whole point is to gauge the newcomer's commitment to the process, and us newbies shouldn't be able to game the system. But I have a couple questions that I hope can be answered:
1. Is it only the introduction thread that counts, or the whole board?
and
2. Is 'sufficient' judged strictly on number of posts, or on quality?
