i've noticed in a few posts ppl use the term "railing" in regards to online poker. what excatly does this mean? playing 4 tables a once?
Railing is observing other people playing. CCers frequently "rail" other CCers play to provide encouragement, support, etc. Comes from live tournament play where family, friends, etc. are seated "behind the rail" to observe play.
This is why you see so many comments in the chat boxes from people not actually at the tables. This also, unfortunately, allows flamers, juveniles, and other species of ***holes to observe and make idiot comments.
A hint when playing on Full Tilt is that you can right click on an observer in the chat box and put them on "Ignore" if they are affecting your play.
