I cannot find 'invites'

[#1]

Hi All, 

I know I have stumbled across these in the past, and been surprised to find invites sent directly from past clients. I've just been trying to work out where to look for these, but can't see anything obvious. I'm pretty sure they didn't just pop up in my messages! If anyone can point me in the right direction, that would be greatly appreciated. 

Thanks.

Are you referring to the Invitations to Interview under Proposals?
