One of the features I missed from Guild Wars was the gentle reminder of how long you had been logged in for.
That's why I wrote this mod. To remind you of how long you've been logged in by giving the message:
You have been online for X hours.
After 2 hours (in Guild Wars) it would add 'Please take a break.'
This mod provides a similar message, but every hour, after 2 you'll get something different than 'Please take a break.' If you want the original messages, you can change the localization.lua file to create your own.
