There are too many people in IT in Zim. Many doing great stuff, and it is impossible to invite them all. The event is free and open to anyone who wants to attend/contribute. Yet again, you are focusing on something petty, getting an invite.... If you read the article:
While attendance is free of charge, you will need register to reserve yourself a place. Please register on the following url: jumpstart-panel.eventbrite.com.
Send him a link to the article if you truly think he's worth his salt. Otherwise if you choose to be a cry baby,insisting on him being a panelist of being "invited", then this wouldnt be the best thing for him.
By the way, I do have suspicions that you are him. Its not important though. Just playing along to help u see reason.
