YAIR is a pretty frontend for the Reddit private messaging system, designed to help you manage it in an organized and time-saving way. YAIR is based on the Gmail interface; you can send multiple message threads or groups of message threads at once, and you can add a calendar to help you keep track of important events. The search feature is an essential part of any good inbox; it can search your entire inbox for matching messages, making it quick and easy to find what you want to read later.
