When using the free demo (http://xenforo.com/demo/) is the Resource Manager included in that demo? From the Admin CP I notice there is a Resources section Applications -> Resources. Is this what the Resource Manager extra refers to, or is this something else? Previously, I have used Sphinx Search (http://sphinxsearch.com) to allow searching of a large number of messages and threads. Does Elasticsearch have similar principles to this? Also, how can I change my display name on the XenForo Community?
