We hit the 200,000 registered user milestone on WorldCat today at 10:09:04 am Eastern Daylight Savings time. We have e-mailed the lucky registered user to make sure he or she is amenable to having a bit of publicity. So unfortunately we haven't heard back yet...but we hit the mark today and we're still climbing! So keep those registrations coming. We'll be celebrating the next milestone again before you know it!
