FGS 2011 - Official Blogger
The Federation of Genealogical Societies named 10 Official Bloggers for their 2011 Conference and I was one of them. In exchange for publicizing the conference, official bloggers received a complimentary full conference registration, free admission to one social event, access to the media hub in the Exhibit Hall for access to Internet and charging stations and access to the Exhibit Hall during off hours.
In conjunction with some genealogy conferences, Family Search often sponsors an event for bloggers. I've attended several of them.
2010 Atlanta Family History Expo - Blogger of Honor
Family History Expos is a company that puts on genealogy events around the country usually featuring two days of workshops combined with an Exhibit Hall of genealogy related vendors. As a Blogger of Honor, I received a complimentary registration and admission to the Friday Night Event plus free wi-fi in the conference center during the two day Expo in November 2010.
