One of the things i like is a perpetual calendar. You can find them on Amazon. I want to make an online version of that via a thread. For example, I make a thread as usual. But I want that thread to become a sticky at on a certain date. Say there is one for 5th July. The thread is already made. When 5th July comes, it automatically becomes a sticky. The following day, it loses it sticky and gradually drops down. It becomes a sticky again 5th July next year. Suggestions? Add-ons?
