I saw on your newly designed site discourse.org that it is possible to “mark solutions as the official answer”. After doing some research I saw that there was a plugin for this, but now it seems to a native feature.
According to this Is there a plugin or option for users to mark "helpful" posts? and this Category setting to enable solutions doesn't stay checked post, this setting should be available when I click on some category, then edit and then settings. However, there is no setting “mark solutions as the official answer”. Is there some additional step needed to enable this?
