In looking at badges, I notice many terms for which I am unable to find a definition on the site. I'm sure it must exist somewhere, but even using the search box hasn't seemed to help. I did also try the FAQ, but it appears to be more geared toward basic use of the site, not definitions of terms.
For example, what is a rollback? I can guess from context. Sort of.
Or, if I want to know what the list of privileges are, I can't use the search box to find that list. I have to know to look under the FAQ, expand "What is reputation", and click either "privileges" or "additional privileges". For that matter, I can't even do a search on reputation in order to get the reputation FAQ.
Basically, I'm trying to figure out how to be less confused without making silly mistakes. :)
