Template:Soa
From HorizonXI Wiki
Used to hide soa content until it is included in horizon: {{soa|text to be hidden until soa is included in horizon}}
does not work to hide template syntax, only plain text. If unsure, test first with an expansion that is already included, like {{cop|text...}} to make sure the content is working with the template and correctly showing when tagged as era content.
to hide template syntax, see Tagging Out of Era Content.
