Nodes vs IDs and what it means to Google ndexed threads
 

I am trying to get some clarity on what will happen to my THREADS that are currently indexed in search engines. Can someone explain the new concept of "NODES" and the recent references of a non-existant "MAPPING TABLE" ?

Will we start getting thousands of 404 errors when we upgrade to VB5?

Is there a mapping table being developed?

In vB3/4 you can have a thread, post, blog, PM, VM etc all with the same id (1 for example) - in vB5 they are all nodes, and every node id must be unique, so something has to change.
