This gives a few results for personal layout communities, but none of them seem to have any profile codes yet.
A collective comm similar to dreamwidthlayouts for them would be very nice, though.

I think a few things are't working with the CSS on the profile pages yet, which causes codes that were made for LJ to look weird sometimes. Maybe a lot of code designers are waiting until this is fixed. I think once that changes LJ codes should work fine as well.
