'Predefined Values' > Country (preValues.php?list=Country) are not used (ordering not used) in modules Ads, Events for 'Create Event', 'Post Ad', search.
I did a quick search for $aPreValues['Country'] in these modules. There are some hits in BxAdsModule. Is this a work in progress or maybe a bug? Would be nice to have predefined values for country everywhere - because of country ordering so that the users most likely choice is on top.
