2. Graphics are fine, but please keep them within reason! Graphics that are too large annoy a lot of people because they tend to mess up some people's friends pages.
3. Please keep all posts rated PG! Anything above PG should be kept behind a LJ-cut with an appropriate warning.
4. Only Harry Potter RPG ads. Thanks! As long as the RPG is dedicated to Harry Potter in some way, it doesn't matter if the community is on LJ, IJ, Blurty, or their own server.
