If there's a subreddit you look at, you can get it as an RSS feed.
For example, say we want to get all of the posts of
https://www.reddit.com/r/yungfreckzunmoderated/.
Make an RSS feed with the following URL:
https://www.reddit.com/r/yungfreckzunmoderated/.rssNote that all you have to do is put
.rss at the end.
If you want the top posts for the day put
top.rss?t=day at the end instead of
.rss. You could also use
hour,
week,
month,
year, and
all for the hour, week, month, year, and all time.
If you want
*ALL* posts to redit with "yungfreckz" in it use
https://www.reddit.com/search.rss?q=yungfreckz&sort=new
