JMK, I went through the same thing - unless you make an event list (as I ultimately had to do for the Kritzerland things), then you have to check each person you want to invite separately. Once you've made a list, then you have the option of sending to that entire list. It's really pretty screwy but it works well once you've done it. UNTIL you do either of those things, no one will get the event. I could send one out, too, but MY list is an LA list so I'd have to do exactly what you're going to have to do - check each thing separately - but I will be posting on my page.
