This plug-in does exactly what I need it to do.  Displays rules with an accept or decline button.  Pretty simple.

The plugin is good but can be better if some problems will be fixed and with some redesigned UI. 
right now, even after the last update, the command "rulesto" not working as it should be. it shows the Rules panel only for those who do the command and not for the target player.  so basically it doesn't do the purpose of the command. 

The UI can be designed more professionally, and the locations, the size, the buttons size, and buttons locations, all of it can be even better. not just that, a fade-in/out option for the panel can be added so that it will be closed/opened more nicely.

An option in config to set the rules more easily than only one line for all the text, it's hard to set, especially when I use a language that is right to left.
and more features can be added, I posted some suggestions and I hope the developer will add them in the future.

In the end, the plugin is good, it does the job except for the bug with rulesto command.

If you are looking for a RulesGUI plugin that shows a panel of rules with some options to set in config, it's the one for you, but,  you need to redesign the UI and organize some stuff because the default design is not that professional.
