In-Game Faction Recruitment System

Long suggestion, so long I have to write some of it in a comment! If a new player joins the server and asks in chat if they can join a faction/if anyone is interested in joining their faction, there's a high chance that either no one offers, or they get no response at all due to the small playerbase. One idea that a certain 1.18.2 factions server (that I will NOT name) has is an in-game command that players can use for faction recruitment. I don't think it should be implemented in exactly the same way (they have a very formal application process, this is a much more casual factions server), but I think the concept could be good for this server. You would use a command (new players should be aware of this, it should potentially be mentioned with a hologram/NPC at spawn, in /faq, etc), on that server it's /lff (Looking for Faction) but it could be "/f recruit" or something else. It would open a GUI with two categories. Factions recruiting members, and Players looking to join a faction. Factions/players should be able to include a description of their faction/what they are looking for in members (in the case of a faction recruiting) or a description of themselves/what they can offer to a faction (in the case of a player looking for a faction). A potential advantage is it can be a more streamlined process. For example, it could automatically list the Faction's civilization (in the case of a faction recruiting), or the player's civilization (in the case of a player looking to join a faction). One thing I want to make very clear - players should still make the final decision on who joins their faction, at least by default. In the case of a faction recruiting, they decide which applications to accept. In the case of a player looking for a faction, the faction they apply to decides if they accept them. (Opening your faction with /f open is in my eyes asking to get insided/betrayed) CONTINUED BELOW
