After some time of absence I wanted to check the Dutch Asterisk forum: forum.asteriskportal.nl, but it looks like it doesn’t exist anymore 
Has anyone information about this ?
Nope
Questions here are okay. English is preferred, as it will garner the widest audience. But, if someone wants to respond in Dutch that’s just fine.
I don’t need to be answered in Dutch. 
I was only wondering what happened to the dutch forum. I’ve been active on that one for many years too, but it seems to have vanished.
