this is a Frequently Asked Question, so I am making it into a new topic.
The Surname Interests Table (SIT) and RootsChat are two different sites. You can change your profile on RootsChat and enter your surname interests, so they will show up on any postings, but they will not automatically be entered in the SIT.
Similarly, you can enter your surname interests in the SIT, but they will not automatically be inserted into your profile.
The idea of the SIT is that it is searchable, i.e. you can search for others with your interests, whereas your profile will only be seen by those who read your posts.
So the best thing is to put all your interests in the SIT and your main interests in your profile, too !
