But even if I did agree with you about the site errors, the huge gaps in any communication are a big issue. It'd be great to know what's going on. And not being able to get an account deletion honored is frankly unacceptable. I've had one pending for close to a month. And having the entire project tied up with one person who just disappears without warning is also a big problem. Administering this instance all by one's self is already impractical. But doing that and also single-handedly running a software project of this complexity and magnitude on top of that is really hard to rationalize.
