 This is a simple form that converts opcodes as server sees them to/from various values used by WoW client.
 Don't expect it to magically give you all the opcodes.
 
-Fields exaplanation:
+Fields explanation:
 Opcode (hex/decimal) - opcode as server sends and receives it.
 Special (hex) - value used in NetClient__ProcessSpecialOpcodes / NetClient__JAMClientDispatch.
 Auth (dec) - value used in NetClient__HandleAuthOpcodes / NetClient__JAMClientConnectionDispatch.
