Hi Gadi Oron, The easy answer to the question you ask below is to download the latest version of Notation from http://www.wolfram.com/~jasonh/Notation.html Basically the error message was meant to be analogous to the error message one gets about the spelling of variable names. E.g. if one enters xtemp=1; ytemp=2; you will get the message General::"spell1": "Possible spelling error: new symbol name ytemp is similar to existing symbol xtemp." This is what I had originally modeled my error message on, however there was too much confusion about this among users so I dropped it in later versions. (Possibly I should have had a more detailed error message). Note this change was included was included in Mathematica 3.0.1.
