Had this thought the other day...a feature where you could set up a notification so that HP messaged you to remind you of something.

Could be breedings, reminders to create shows, pay for show spots, etc. 

Players could set them up to send on a certain date.

I would definitely use this myself, haha. I'm not sure how practical it is programming wise but I can ask.

I would use it, too, although I'd be so paranoid about forgetting something that I'd keep using my Excel sheets anyway xD

oh god this would save me all day EVERYDAY

this would be amazng, i'd def use this feature for breedings
