In Monobook, the follow button is still there on all pages so if you switch to Monobook in the preferences, it'll be there.

For doing it manually, just add '?action=watch' without the quotes to the title of the page. It should then ask you if you want to follow it, click okay, then you should be following the page then.

Hope this helps.
