Thanks so much for all the input. So if I don't have my Event synced to a SFDC campaign and I create a list inside my Event, those leads will not all sync into SFDC, correct? I will add a step in my campaign flow to sync on form fill out. I did a test on a seed list which seemed to work, but I'm nervous b/c the list in question has ~3K in it...
**If I don't sync with the SFDC campaign, then don't I lose the ability for GTW to update SFDC with attendees and no shows after the webinar?**
