For those who do not know, iCal is a standard calendar format used by many applications (Microsoft Outlook, Google Calendar, Apple Calendar, and many more). I think it would be awesome if Roll20 could have some sort of integration or notification system for when games you're both running and playing in are set to play next. This would allow you to sync it on your calendar on your phone/tablet/computer with notifications to make sure you don't miss any games. This could really be done in two ways: 1) Emails - To do this, you 'd need to set it up so every time a game time changes, an email is sent out with an iCal event or modifications. This should be fairly easy to do, as I've seen some code to do it myself, not really different than sending any other email but with some special iCal tags. 2)Calendar Integration - This would probably be more complex, but also more powerful. With this, Roll20 would need their own calendar setup for eac member, with an iCal feed that could be integrated into other calendar programs. This would be a challenge as you'd have to be able to sync all the games and changes to each player calendar, but it is definitely feasible to do. I would, as a player, be willing to become a supporter for a feature like that, as it wold make my life easier (Will be subbing soon anyway as I'm planning on running a game and dynamic lighting is awesome). It'd also be awesome as a standard, free feature, but just wanted to put my opinion on that out there.
