That's one thing the team is working on -- originally it was just P.Win and then the other .wins sprung off from there. There should be a tab at the top of the screen with some generic communities

There's also https://communities.win/c/all which can be hit or miss given how small some communities are. No, they're not separate websites but they look like they are given the drastic theme changes from one to another.

There's a lot of potential here, truthfully.
