The AllSigns plugin has two permissions. The permission allsigns.create allows creating new signs, and is default to OP only. To use signs, players need the permission allsigns.use, which is assigned to all players by default.
📄️ Creating a new sign
To create a new AllSign, first place a sign and write #as into the first line.
📄️ Editing or removing a sign
To edit a sign, touch it with a golden pickaxe.
