i will get only one page with a small "welcome-text" and the next following events. No way to login and see some other infomration aka Timeline, last photos, Groups, etc.
when the visitor click on a event he will get information about the event but no other information. Then he could use a login button and then he will get a "small" login maskto login or register to create a account.
they never have to see some like the normal JOMSOCIAL Start page.
