Hey guys! My site is using XenAtendo to handle video game players playing together. Since there are so many (often 100+ in a day), I want to add functionality that when an event starts, all members who RSVPd get sent an alert, and at the end of the event, all members who RSVPd get sent another alert. I've been poking around in how to do that and it seems like it needs some kind of listener, and alert model: Listen for events beginning/ending Make an alert model corresponding to each When the listener catches an event beginning/ending, loop through the RSVP list, sending corresponding alert to each username But I have no idea how to do that, and I haven't been able to find any tutorials on doing so -- I've just gathered that from my personal programming experience and poking around in the XenAtendo and xenForo files. Does anyone have any pointers to help me do this?
