Auto-finalize and the resolution center itself have been stopped until the site has been up for 48 hours. However, normally to request an extension you simply click 'resolution' (when it becomes available) beside the order that you wish to extend and you'll be taken to the resolution center. There will be a number of options, simply select the 'extend' option, type a comment if you so wish and wait for the vendor to either accept or reject your proposed resolution. Most vendors are more than happy to agree to an extension. Once an order is in the resolution center it will not auto-finalize, but if the buyer and vendor cannot come to an agreement then a Silk Road Administrator will make a final decision based on all the information available to them.
