Thank you! I clarified this with further editing at the top of my post. Thank you for asking clarification. 

I had just created the event. I didn't invited the friends yet so the people who were invited wouldn't see nothing in the description of the event. 

I wanted to linked them here so they aren't invited to an event where there isn't any info at first, so I posted here then hop right back to Facebook, use the chrome addon which select all the friends automatically and them press invite but then Facebook said I was to fast to invite the people. 

They must use something to detect this kind of automatic invite addon so it doesn't become a spam fest were everyone is invited to something ad infinitum.

Like I said I'll do another event when I'm unblock to invite my friends but won't make the same thing as I tried doing here cause it won't work.
