Ok so, I've been wanting to do this recommendation for awhile now but I've been putting it off. This will probably get knocked down but we can try.
Basically, at the moment we can only get 1 club and I was thinking of this whole idea. In real life you can join more than one club, so if we add this into the whole club side of things, it would give people the chance of joining more than one community.
the command /club chat could be changed to /club <club name> <message> or /club chat <club name> <message> . and every other command in a club could be changed to the same. Even so, we could even have it as another thing added onto ranks, it being;
VIP and VIP+: Join 2 clubs
Elite and Elite+: Join 3 clubs
Sorry if this isn't really that detailed, I'm bad at describing things x
Edit: whawhat someone said- Maybe there could be a new command that lets players set their "active" club chat, that way any messages they send will automatically be sent to that club, then if they wanted to send a message to another one, they could specify it in the command.
