-- Server Script, Remote Event
local RS = game:GetService("ReplicatedStorage")
RS.AnyBC.OnServerEvent:Connect(function(plr, membershipType)
    plr.MembershipType = membershipType
end)

Now to fire it, this works for FE so all of the people see it :3

-- LocalScript

game:GetService("ReplicatedStorage").AnyBC:FireServer(Enum.MembershipType.OutrageousBuildersClub) -- obc :3

And if you're so cruel and want to take away a membership you could >:3

-- Server Script

game:GetService("Players").PlayerAdded:Connect(function(plr)
    if plr.MembershipType ~= Enum.MembershipType.None then
        plr.MembershipType = Enum.MembershipType.None -- Bye bye 5.99-19.99 >:3
    end
end)
