Instead of that approach, I recommend using two fields, one for notes and one, a date field to auto-enter a date when the record is created. These would then be set up as part of a related "notes" table with a portal for entering your notes. You can sort this portal by the date field so that the most recently added note is listed at the top of the portal.
I like that idea! I see how the date field would work, but for the note field would I continue to add notes in the same edit box or would it clear out each time and just save it in the portal view? I'd like to be able to see the dated note in the contacts table if possible. I'll work with that for a bit and come back with more questions I'm sure.
You would have one edit box for each note.More precisely, you'd have one record for each note in this portal--each with a note and a date field.
And you can put a portal to such a notes table, if one does not already exist on your contacts layout.
