All the nodes, writeups, users, groups, etc. in the E1 or E2 database are available via node_id. Using this in the URL can help in accessing weirdly titled writeups.

For example, try getting to the true " node (the one in which my writeup starts with "This is a double quote.", not "This is a bad node!"). Really a pain, huh? Try going to instead. Boom. You're there.

Of course, some things are only viewable and changable through direct modifications to the database tables.
