… want to create an unique community without reference to WoltLab,
… want to hide the software used to create the community because of security reasons,
This is nonsense... It's no problem to identify the software used, if a user wants to... Doesn't matter if it's WSC, XenForo, IPS, vB, or what ever....Normal users may not know how to do this, but for experiecend users, it's definitly not a porblem.
