How to incrementally update a notes field when a record is updated?
I'd like to set up a text field that is updated and tagged with the account name and timestamp when the record is updated by someone. E.g. there could be a field called "Notes" and each time someone adds to it, the old text remains but the new text goes in below it with a notation about the accountname of the person who added the new text, plus the timestamp.
For example, this is seen in bugtrackers when the new text is added each time someone updates the description, and the comment field has the user's name & timestamp. I can't figure out how to do this, any hints would be greatly appreciated. Thanks,
