I am always looking for websites that feed my faith and increase my knowledge regarding the Catholic Church. Here are a few of my favorites:
St. Paul Center for Biblical Theology - lots of information and free bible studies. Started by Scott Hahn.
EWTN - lots of resources. Love the archives of podcasts.
Lighthouse Catholic Media - download mp3 lectures on Catholicism
My favorite Liturgical Calendar -- through catholicculture.org
Daily Readings for Mass and meditations --at the Word Among Us
www.dailygospel.org -- this also has the daily readings and related responses written by saints/doctors of the Church. I also have this on my phone using Evangilizo (Android)
CatholicMom
Catholic Bible/Catechism reading plan:

I'm sure this list will keep growing, too!
