Hi, and welcome to the LCF info. and member site! You are welcome to browse around on this site to learn more about LCF. We also has some stuff on the Lawrence site (FAQs, doctrinal stuff, InterVarsity links, etc.).
Of course, the best way to get to know LCF is in person. Check the announcements for meetings (usually Wed., 9pm, campus center) or drop a line to someone on the leader list.
