having logged on, each user was taken direct to their default main index page, known as the "welcome page". for standard users, this would be page 1a, the general top level index to the whole of prestel. however, if a user signed up through, or later joined, products or services from major ips, such as club 403, micronet 800, prestel travel, citiservice, etc., they would be given a different welcome page, so that after logon they were routed directly to 800a, 403a, 747a etc.
