When a freelancer who is in My List becomes inactive so Upwork is not listing them in search, it would be nice to put a marker in My List letting the client know.
Alternatively, you could add Last connected: [date] on their profile.
The reason I'm asking is because I've already invited two from my saved list who never responded to the invites. Since both are newbies without any work history, but with a skill not easy to come by, I can imagine that they got bored of Upwork and abandoned their profiles.
Hanging and waiting for them to show a proof of life is frustrating and a waste of time.
