Auto Adding a Page Upon Account Activation

I’m trying to auto add a page for each member when they visit the account activation page (which would be once, so one page gets created per member). I have the following in my theme’s account activation template file file, and it’s creating the page just fine, but can anyone help me out with how to get the page title to be the new user’s login name or even their ID#? As it is now, the page is being created exactly as I need it to, but with no title. The purpose is that I want to link to the user’s page from their Buddypress profile.
