OK. You'll have to make another folder in the custom logs folder, so label it Reward (or whatever you want the command to be called).
Here's what the commands should look like:
Enable User (Elevated Access) for ALL of these!
!reward
@if@[@readfile@[Reward/@user@.txt]||||!rewardpass||!rewardmath]
!rewardmath
@if@[<=||@calc@[+|@unixtime@|@readfile@[Reward/@user@.txt]]||0||!rewardpass||!rewardfail]]]
!rewardpass
@user@ received <amount> @pointsname@! @editpoints@[@user@|+<amount>] @savefile@[Reward/@user@.txt,@unixtime@]
!rewardfail
Sorry, @user@, you can only use that command once.
