When I create a sub-site it is automatically creating a link the top link bar of the main site. I don't want a link to be created when I create a new subsite. Is it possible to change this?
when you create a subsite at that time you have this option wheter you want to add this site in top Link bar or not.
- Site actions > New Site on this page click on more optins
- On this screen after entering the Title, Descrption and if you scroll down you will see the options for navigation. Display the Site on the top link Bar of Parent Site, this option is yes by default. once you select No, then it will not appear in top link bar.
you can navigate to Site Actions -> Look and Feel Section -> Navigation and set the links you want to see and hide using Global Navigation
