Pls learn to use periods, it's very hard to read sometimes XD. But yeah, most of the players are on hiatus for a bit between work or studying. As for white listing, or starting a new world, I think you might have some opposition to that considering that quite a few people have put in a significant amount of time and effort into their builds. Mindcrack is a bit of a unique case, they're an amazing community but for most of them Youtube is their job.
As for a whitelist, I'm all in favour, but a lot of our former regulars were not GC members so that's a decision up to the admins.
