Vbulletin 4 has a "Use Remote jQuery" with; Google, jQuery, and Microsoft. being listed.
Your using CloudFlare jQuery 2.2.0
Any reason why you did not default to one of the built in selections? Are there any performance enhancements between any of these? Would it be worth while to add Cloudflare to the available default configuration list? Could not be too difficult... Will vBulletin 4.2.x run under jQuery 2.2.0?
Would be nice to have a collapse option once expanded
