Say you left a feedback on a model...then changed your mind, for better or for worse.
Just type in ANOTHER feedback and it will automatically delete the first one.
If you want to add a second feedback to keep, then copy and paste the first one in before the new feedback.
When I first started on this site, couldn't understand how, when I worked with same photographers more than once, how their first feedback always got deleted, in favour of the latest one.
Then another member told, make sure the photographer copies and pastes the first one, or subsequent ones, THEN the latest one or you will lose the initial ones for ever.
Still only seems to count as ONE good recommendation though, for each photographer, even if I work for the SAME photographer and he gives me half a dozen good recommendations...on different dates, one after the other...
A lot of togs didn't know that until I explained to them.
