A question about maximum Crysta.

speaking of which, never heard of those Click-n-buy myself.

It was a payment provider that SE used for a short time early on. It is absolutely true, as Stompa said, that they were really shady, and there was significant backlash from the userbase about it at the time. But it wasn't anything nearly as dramatic as they suggest. And today, as I said more than once before, SE now uses a worldwide recognzied payment processor that most people can pay through without issue. I'm legitimately saddened that the incident triggered somebody to never use direct online payments ever again when it's normally quite easy and safe to do so. It was before SE made that dumb decision, and it still is today.
(Yes, I actually said "SE made that dumb decision" - some people think I'm a white knight that believes SE can do no wrong)
