Hi! I'm pushing my feed of upcoming events up to my newsletter and I don't want to show events that have already passed. Is there a way to hide/delete posts with pubdates older than the current date? The custom feed I made pulls in data from events when they're 8 days in the future, but I can't just say, "show x number of posts" because some weeks there are 4 events and some weeks there are 10.
I'm pretty new to managing data with RSS, any help is appreciated.
