I’m going to watch the NCAA national championship game tonight and manage 200 LinkedIn invitations. Under the settings menu it would be possible to convert to only allow invitations from people who know my email, but it says the current open setting is recommended. 

It turns out I have zero sent invitations that are unaccepted. My queue for sent invitations is completely clear. My received invitation queue is out of control. Some of the invitations come with a message and others are just seemingly random. 

The first 100 are now processed. I’m working on the second page of invitations now. 
I’m now all caught up on invitations. Maybe I should spend some time sorting out how all those contacts got imported. I asked LinkedIn to remove all those backed up contact lists.
