Now that we're basing the next Virtuas' website on Drupal, we have to make a decision about which blogging engine to use. Is anyone out there using Drupal for blogging? Does it support multi-author blogs? I'd much rather use Roller for our blogging engine. However, if we have two different engines powering our website - there won't be a way to search both sites. We can make http://virtuas.com/blog look just like http://virtuas.com, but if searching one doesn't grab results from the other - it seems like it might not be worth it. Anyone know of a way to integrate Drupal's search index with Roller's?
