I have already reported that the Compuserve Foreign Languages Educational Forum, FLEFO, has become The Languages Forum.
It appears that if you type FLEFO into a message there, the word is replaced by the Compuserve computer with #### (see thread on Translation Journal in the Transl/Interp MISC section). F-L-E-F-O gets through, though.
(Found via flefo.org, the sanctuary for those who want to talk about languages and don’t like having their messages deleted).
