Two Things I Couldn't Figure Out from the Social Network series

The social network series was great, but it seems like it ended a little early. There are two issues I haven't been able to resolve based on the info provided in the videos. The first was how to create status pages that actually link to each member. I want to be able to visit John's page and see John's posts and see Sally's posts on Sally's page, not my own as the logged-in user. Basically, I want the old Facebook wall. The other issue I was not able to resolve was on the Liking system. Because of the use of the repeater when one post was liked in a status feed all of them were automatically liked. These are the last two things I need to fix to get my new profile system running! Please help!
