Well, I just updated the core version of the Drupal CMS on the Pages of Fun from 6.12 to 6.13 and it went pretty smoothly. One thing that I did discover is that it pays to update all your modules before doing the core update. I had earlier tried to update and the system completely failed on install because of a problem with the out-of-date Admin Menu module. Only a complete reversion to the backed up files saved me. Backing up is ever so very important in this whole process. Anyhow, I am really loving Drupal and I hope to build more sites with it in the future.
