Ya' I know...its hard navigating the LinkedIn website... I got this info via an e-mail alert (today...a week late) sent by LinkedIn... because I'm a registered LinkedIn 'follower' of KAUST. I just now tried to go in as if cold-turkey (like you did) & had a hard time.
Ist; I think you probably have a 'basic' (free) account set-up at LinkedIn... then, type the word 'KAUST' into the searchbox titled 'people'... wait for the drop-down menu before hitting enter key... note the selection & hit the tab titled : Groups KAUST 329members... then hit the 'discussions' tab at the top of the KAUST page.
