@Ruskofff yeah so the issue is plainly obvious.
First, people need multiple accounts to post, one here and one there even though in both places it's the same person.
Second it makes posting content that may be related to the other difficult, in that the topic may be. I'm having issues with XCP-ng, but in fact the issue is something in XO or vice-versa.
Having a unified community for that, and categories within would quickly allow anyone in the community management team to simply move a post, change or add tags and help find answers way more quickly.
Granted, there is no promise that everyone using XO is using XCP-ng they could be using XS. But certainly a large portion of people using XCP-ng are using XO.
So why continue separation? It's only a negative.
