Well, actually Karei replaced the website with the text "We are sorting out this mess", so he still must be around to have noticed this.
Karei is kinda difficult and hard to understand because he is mainly a businessman and not someone that cares much about Ragnarok Online (or is very good at programming). On the other hand his strong will to make money out of his projects is exactly what makes him good. He always cares about his servers unlike many other server owners who just launch it and then stop caring. He still needs good and reliable developers (paid) and this is actually the main reason why he closed the servers and didn't open v4 yet. He won't start anything until he is 99% sure his project will be a success.
On-topic: eROv2 was best. :-)
