I see you have trouble with the cronjob.
Set it up as "wget" and not php!
Like this: /usr/bin/wget www.yoursitename.com/components/com_community/cron… >/dev/null
That will work for you, but video upload will still don't work in jomsocial! There is a major error in the software, and support can't resolve that problem. More than you and me have the same problem.
You cover photo is spot on... and your slogan, from The Jerk, hilarious!
