Solved. In case anyone else uses TF and wants this functionality, I added the following two macros. One logs tells you send, the other logs received tells. These are written to the file 'tells.txt'

/def -mregexp -F -p1 -t'(.+) tells you ' tellRecv = /test fwrite("tells.txt","%P1 tells you, %PR")

/def -mregexp -F -p1 -t'You tell (.*) (\'.*\')' tellSend = /test fwrite("tells.txt", "You tell %P1, %P2")
