Very simple to set up and use. While there are some features I wish existed e.g., history of submissions or the ability to leave a comment with your approval / denial; I cannot rate lower than 5 as you're a legend for updating this.
This plugin was real great but for 2 things which is why its minus 2 stars.
1. The /build list brings up a nice little list but the list has like 15 buttons, 12 of which do nothing (they show me running the command "/builder1 <name>" in console?) and the other 2 "Approve" and "Deny" do the opposite of what they should. "Approve" denies the build and "Deny" approves it. I just got a friend to fix all this so its not an issue from me anymore but this download likely still has this issue.
2. When you approve or deny a build there is no list or anything that shows the approved or denied builds. They are just deleted. They don't even show up in a list somewhere saved in the config files.
I know that this plugin is not a resource that the author is maintaining for the general public, but rather it was made for personal use and was given secondhandedly to the public and that is fine. Just highlighting issues I found.
Otherwise this plugin so simple and easy to use that its great.
