Could we perhaps have a mouseover effect (similar to the email read) on the last logged in date on a profile to show the time a member first logged on that day?
I've had a couple of instances now when I've phoned the model on the morning of a shoot only to get cancelled on and an excuse that they couldn't log on to send a message, but on leaving them negative feedback later I've seen they have already logged on that day, I just don't know when.
All models booked have my number and email address but the latest cancellation chose not to phone/txt or email but gave no reason. She said her internet connection was down so she couldn't get on line to message me. When I went on to her profile an hour or so later after I called her, I saw she'd already been logged on.
Crucially, I have no way of telling whether she'd logged on before or after my phone call.
