This is actually something i have been asking BBO. Its clear that you can put in a colleagues user name and you will be able to see some hands. But there is a message that says some hands are not shown for security purposes. The previous commentator indicates that this is an intended feature. i was hoping it was a problem with my user profile and I could fix this. Someone is instructing me and it would be far easier for him to view my hands than me exporting the hands to him. He can see hands we played together, and apparently some robot stuff but definitely not other ACBL virtual club games and apparently insta tournaments. I cant imagine why this is protected if they allow some things to be viewed and it definitely is a limitation for teaching or review. Wish BBO help could read these comments and consider whether these restrictions make sense
