LJ-Sec is a bulk journal entry management tool. It allows you to bulk change post security, delete posts, find and replace items, repost journal entries to other LJ-compatible servers, and other assorted odds and ends.
0.71 had a minor but annoying bug which stated that a configuration file was locked when you opened the application... this fixes this problem.
