leveragenews_feed is a feed for the Leverage Newsletter on LJ. You can subscribe to the feed here on DW and see the newsletter on your reading page. If you're not familiar with the newsletter, and want your fic, vid, meta, etc. listed, check out their user info for the comms they watch.
Leverage on Delicious is a personal project of mine, that tags all the newsletter links for fic, and allows you to search by genre, pairing, rating, fandom and author. There's a link on the Delicious page to the post where I explain in more detail what I'm doing.
Just a note to avoid confusion, I'm not one of the people who makes the newsletter, I just happen to think it's awesome.
