The actual entry is at blogs.perl.org. However, here's a few extra notes about that site:
It's much more stable than last time. Aaron moved it to a new server and Dave set up MT. The templates are on github along with an issue tracker.
Barbie talked with Dave and myself at the London Perl Workshop (lpw2009) about the site and I wrote down all of his suggestions and they've now been added to the issue list. We look forward to more people trying it out and Dave has a post asking for more feedback. Also, he's aware that several people only made it partway through the registration process. Drop him a line if you're affected and he'll clear it up for you.
I can't thank Dave, Aaron and SixApart for all they're doing to create a modern blogging platform for us.
