CamelCasing should be able to be turned off for a whole block of text, not just one or two words. We have thousands of pages of legacy twiki that depend on camelcasing and have been entered into our Confluence system. Consequently we have CamelCasing turned on at global level. However, newer users tend not to like CamelCasing, or are experiencing problems with CamelCase links related to source code postings on wiki pages.
Having this option set on a space by space level would also be very helpful. http://jira.atlassian.com/browse/CONF-6526
