1. In serverCmdMessageSent, change the %victim in the first if statement to %client.
2. In serverCmdUnmute, you tested to see if %victim is actually muted before defining %victim.
3. According to Destiny, change all ".BLID" occourances to ".BL_ID". I haven't looked at how Blockland IDs are stored in awhile, but BL_ID sounds more right.
