I just completed my first webinar on using the online trees at Ancestry.com--we focused on integrating census and other Ancestry.com databases and images into your file without confusing yourself in the process. It's easy to really mess things up if you are not careful.
Here's what one attendee had to say:
"Thank you for the webinar. I am just now entering our family tree after much research. Now I have a better understanding of how to do this part more accurately."
