From what I have seen, multiple Online Accounts occur thru Subscriptions not being associated with registering of the Family Tree Maker program. The past versions of the program should have resolved that problem.
If you are talking about Submitting your information to the World Family Tree Project, from within your Family Tree Maker program, that will become available on the WFT CDs and the online version of the WFT Project. If you use a Online Version of Family Tree Maker, I dont think that others can view that information nor search for it. Its the WFT Submission that is important for others to see. A User Home Page is another way of sharing information.
