I found it.... singsong I know what it is... /singsong Tagging: Baseball; the act of tagging a runner (off foll by out) in Baseball by putting (a runner) out by touching with the ball or hand holding the ball [18th c.: orig unknown] So, it means I think, that anyone caught running through the forums trying to touch base three times or trying to reach the other side of the forum has to avoid the moderators touching them with a ball held in one hand or they're "outta here"... :D Took me ages to find out what the "official" definition was. Cool, I also found out it was gang markings on turf or indentifier graffitti. I wonder what it has to do with forum threads though? Maybe it's just moderator terminology for "having a bad hair day" looks around and wonders how fast he'll have to run to get over the other side before getting caught
