• Book the photographer and videographer
  We've got a photographer, but we haven't chosen a videographer yet.*
• Book entertainment
  We haven't even started on this one yet. Ack!**
• Register
  We've registered at two stores with physical locations near our families and online options (Macy's and Crate&Barrel; we're considering adding an Amazon.com registry as well if people actually end up using these).
• Purchase a dress
  I haven't bought my dress yet, but I have picked it out.***
• Start meeting caterers
  Our venue provides catering.
• Reserve block of hotel rooms for guests
  We found a hotel with a free shuttle for guests to our wedding venue! How cool is that?
• Launch a wedding website
  Done. We sent out the URL with our Save the Dates.

* Update, 7/29: We booked a videographer! Only nine days late... I consider that a success, and relatively on-time.
** Update, 8/11: The DJ is booked. One one hand: thank goodness. On the other hand: I'm terrified.
*** Update, 8/25: I bought my dress this weekend!
