GEDCOM files
Recently I had some issues trying to upload my GEDCOM file to a certain website. I forgot about it for a while and then this morning I uploaded my GEDCOM file to a different site and it worked just fine. I realized that some genealogists might have the same trouble or may not even understand how GEDCOM files work. So here is a link to an About.com article, GEDCOM 101, written by Kimberly Powell explaining how to create, read, and share your genealogy research via GEDCOM files.
