I agree with the successful / good comment.
Umm, wordplay in text battling usually refers to splitting up a word into two different words as one example. There are many different forms i suppose, basically just manipulating words is wordplay in text at least.

one example from UPN:
Opponents, someone and Cal

i dont remember the exact line but cal's opponent split up the word "calender" to make
"im the cal ender" . theres one example.

i really dont care to get into an argument about which is harder and the similarities and differences. im tired of typing tonight though i usually welcome it as something to do.
