Now we need someone who is equally bored to categorize!
Categories I can think of off the top of my head:
-Emotes (dance, clap, heckno, etc.)
-eq2.ini settings (cl_ui_skinname, cl_ui_subdir, etc.)
-Parameter commands that aren't useable in OnEvent scripts (/show_window, /mood, etc.)
-Parameter commands that are also game settings and thus ARE useable in OnEvent scripts (master_volume, combat_music_volume, r_shadows, etc.)
This will probably be me tonight.
