I heard a rumor online that there have been many thousands of registrations for the free RootsTech Connect. I can't confirm that rumor but I would not be a bit surprised if the numbers were conservative. For the user or attendee having a free virtual conference provides many of the benefits and only a smaller number of tradeoffs for the average genealogist. Unless you happen to live within about 50 miles of downtown Salt Lake City, Utah, and wanted to attend an in-person event, you would need to obtain a hotel reservation, arrange for transportation, obtain a hotel reservation, and plan for food during the conference. This could run into hundreds of dollars or even thousands depending on the hotel and or the food you intend to eat.
By registering, you are not obligated to attend any particular number of presentations. The advantage to you is that you can now see overlapping classes at your leisure instead of being turned away depending on the attendance and the number into the class before you could get time to register. The Family History Guide will be presenting a couple of classes. We may also stream some classes during the conference. Who knows?
I am looking forward to the virtual RootsTech but I will be missing seeing some of my old friends and making some new ones.
