I am trying this now...
If you go to
https://glassfish.dev.java.net/ and you are not a member of the GlassFish project, you will see the following text in the upper left of the "main" part of the page (below the page header and to the right of the navigation menu)
Request project membership/role | Watch project
click on the 'Request project membership/role' link....
That will take you to a page where you can request the Observer role...
