My Ancestry sub expired at the beginning of April, and I am still able to view, and edit, all my trees!
I no longer have access to census, BMD, and other data - so I can't attach an image to my tree.
But I can add my own data quite happily.
To download a Gedcom:
1. Open the relevant tree.
2. Click on "Tree Pages" and "Tree Settings".
3. Under "Manage your Tree" on Right-hand side, click on Export Tree (green button).
4. When it's finished processing, click on "Download your GEDCOM file" (another green button!)
