Crap init...
Oh yes. Soo glad to be out of it all.
Trying to fathom out how Linkedin works. It may take a while. . .
It's all very non intuitive in it's interface.
I have an almost accidental LinkedIn account with the briefest of profiles and people I knew when I was working keep inviting me to link and endorsing me and even contacting me - rather smile making.
LinkedIn has become significant if you apply for any professional job. We always used to search for the candidate's profile when we did interviews. No profile = sus, profile not matching CV even susser and more than once the profile made us look at them better than the CV indicated.
