HookEm

Hello all, I am not sure if I am on the right board for this question so if not please forgive me. I play Battlefield 2 and I have joined some servers that has a greeting when you join the game i.e. Welcome (player name) To (server name). I have asked on BF2 related forums elsewhere but the only responce I have gotten was the question do I hack much. I am at a lose here. If anyone knows what this is or where to get it please help me with this. Thanks in advance for any and all help. HookEm
