Simple. I think using the command /r should give you an option to see your rupee history. Option 1: Rupees: 1,234,567 [Learn More] [View Log] Option 2: Rupees: 1,234,567 [Learn More] [View Log] My reasoning is that /rlog is an odd command. I sometimes forget the command. Usually you can do /command subcommand to cycle through to the right command, but /rlog is its own main command. I keep thinking "Is it /r history? /r log? /r list?"
You know you can just look your rupee history up on your forum account. Why would you need to do so in game as well.
Ease of access. That's like saying why have the ability to private message people when the forums exist.
Not really, as dms in game auto-refresh and play a notification sound for the other player, while forum pms need to be manually checked. /rlog already exists, Tower is just asking for another way to access it. I wanted to test the command, but couldn't, as Minecraft only lets me play the demo world, but I read it on the wiki.
