I doubt the AWN staff would post it as news if they didn't confirm it first.
The user account was created the same day as the announcement:
http://amigaworld.net/userinfo.php?uid=10832How does tomazkid respond to the question over whether the message is from Evert Carton:
http://amigaworld.net/modules/news/article.php?storyid=5904&start=0#79264Don't know why Jorit2, perhaps he forgot the password to Jorit account?
Anyone who was semi-competent at checking the validity of a post would know why a new account was created, as they'd have to question why it was done (if an explanation wasn't offered in the first place).
Also, the wording of the message is rather unprofessional in tone, certainly not how I'd expect a high ranking member of a company to conduct themselves.
So, in summary, whilst it may turn out to be a genuine message, the newly created account, non-professional tone and incompetence of AW.net moderators does not convince me that the message is genuine. I would suggest a personal message from Evert on the Hyperion website is a better way to officially announce a resignation, if that is what he has chosen to do.
