FormLicense
For some (such as survival) servers, they hope that players without a white list can enjoy some unique content (such as sightseeing or features) of the server. If you are a server owner, you can choose formlicense to do this.

Feature

• Simple and lightweight enough
• Most (existing functions) can be customized
• Players without a license(permission) will be in adventure mode
• Player without license can't pick up, join portal, hit or be-hit, be-targetted.
• Send information to players when they join
• If you want, players will not find all traces of FormLicense in the game.(More fully display your brand)
• Plugin functions are constantly update and open-source
• If you want to prevent unlicensed players from doing anything, you can request it on the issue page.

Apply
Minecraft(Spigot 1.13-1.18.1) Only tested at 1.18 and work is perfect.But the api is Spigot-1.13,so i think it also worked between 1.13 and 1.18.
If you tested at 1.14-1.17, please tell me the result

About Plugin
You can reprint the plugin on any minecraft website. But you must let me know (such as scoring on spigot or sending me an email: [email protected]) The plugin is still in the early construction stage and is constantly improving its functions. Therefore, the existing content may not meet your needs. Please forgive me. If you can, please actively communicate with me and request new functions. If you like this plugin, I would be grateful
