Once you have completed the registration process and become a Family Member, you may begin to add your family tree to our database. Eva and Robynne have given you the steps you need to take.
Since you have over 2500 people in your gedcom file, I strongly suggest you split your file into smaller segments for processing. You will be able to finish the review and importation of the individual members much more quickly if you have a small file. You will not be allowed to create profiles through gedcom import for anyone born prior to 1700.
Your gedcom report also indicates you have no itemized sources. You will need to add sources to your profile pages.
