Blogger discovery

I've just found out that Blogger only gives you access to the most recent 5,000 posts on your blog. Granted, that sounds like a lot, but on my memes blog, I'm up to nearly 6,500 and I can no longer edit the the first two years' worth of posts. Which, ironically, are the ones I'd like to edit and/or delete.

This is annoying. I maybe have to port over the last posts somewhere else. Or maybe block access to to the early years? I dunno....
