I made the mistake of attempting the multisite feature of WordPress. It seemed like a good idea at the time, I could manage any number of blogs from the same admin panel. The only problem was, if it conked out, it would conk out all my blogs, which is exactly what it did.
I did manage to save the claycomix blog, but when I put it back together none of the links were the same, which killed all the links from Tumblr and Twitter. It also killed all the links within the site itself.
I’ve learned my lesson, and started this again on its own, with no multisite. It’s a pain doing everything again, but it’s my own damn fault.
