done with the servercmd, testing now.. (sorry, dren, I really wanted to make the servercmd)
Edit:
Script_ClearGroupscommandToServer('clearBrickGroupList',"BL_ID BL_ID BL_ID");
Do not /clearBrickGroupList BL_ID BL_ID BL_ID for it will only clear the first one.it will list the owners' name or their BL_ID WITH proper grammar:
1:
MARBLE MAN cleared Name's bricks
2:
MARBLE MAN cleared Name and BL_ID:999999's bricks
3+:
MARBLE MAN cleared Name, OtherName, and EndingWithS' bricks
