Hi Suzanne, I'm puzzled as to the intended use of the Exhibition Mnemonic field myself. I can tell you that when you create a new Exhibition record, it auto-populates with the first 32 or so characters of your exhibition title. It might also be useful for you to note that each exhibition does have it's own ID, just like Object IDs, though it's not visible on the record. In version 2010 this ID (called a DexID I believe) is fully visible on each exhibition record. If you plan to upgrade soon you might just want to wait it out instead of adding a different number to the mnemonic field. Also, just a follow up to Chad's suggestion, which I like very much - you can configure TMS to allow duplicate mnemonic values and exhibition titles. Its in Database Config > Exhibitions.
