Since the release of the new PSN Communities app, Octolus and I have been reversing their API and so far it's pretty much all mapped out. We've been updating my project psn-php with new features as we find them. Using that API wrapper, I've created a tool to search PSN communities and view them in a web browser. This was just something I threw together with a few hours of work tonight so I still have some things I want to add/change but for now, it's up and running.
Go here: PSN Communities and search for the name of a community. It uses the same search functionality as the PS4 does so you should get identical results. You can then click on a community name to see the actual community. You can even copy the link for the community and send it to people to show them your community. Here's one of Octolus' communities:
PSN Communities | PlayStation Home Veterans
That's pretty much it. I'm still tweaking the community page design but I tried to mimic the same style as the one on PS4. If you run into any issues with this, please post in this thread.
Hope you like it!
